Definition, Examples & Applications with Videos [1]
A solution is a homogeneous mixture of two or more pure substances on molecular level whose composition can vary within certain limits. A solution has two components (substances) known as solute and the solvent.
Excess dissolved solute crystallizes by seeding supersaturated solution with a few crystals of the solute.. For example, the object of pan boiling is the production of a fine even crop of sugar crystals
Basically, a crystal surface maintained in a solution will only grow if the concentration of the solution is maintained at a level greater than the saturation concentration. Supersaturation in Phase Change (Crystallization and Condensation)
13.2: Saturated Solutions and Solubility [2]
– To understand the relationship between solubility and molecular structure.. – To demonstrate how the strength of intramolecular bonding determines the solubility of a solute in a given solvent.
If the molecule or ion happens to collide with the surface of a particle of the undissolved solute, it may adhere to the particle in a process called crystallization. Dissolution and crystallization continue as long as excess solid is present, resulting in a dynamic equilibrium analogous to the equilibrium that maintains the vapor pressure of a liquid
\[ solute + solvent \underset{crystallization}{\stackrel{dissolution}{\longrightleftharpoons}} solution \nonumber \]. Although the terms precipitation and crystallization are both used to describe the separation of solid solute from a solution, crystallization refers to the formation of a solid with a well-defined crystalline structure, whereas precipitation refers to the formation of any solid phase, often one with very small particles.
Reading Comprehension: Application Questions [3]
The author of the passage would most likely describe a solution which can still absorb more solute as. A solution that can still absorb more solute is not yet saturated, which means that it is not at equilibrium.
A supersaturated solution is one in which there are more solute molecules than can be normally absorbed by the solvent.. A solution that is at equilibrium is saturated, which means that it cannot absorb any more solute
A solute dissolved in a solution may be in a solid, liquid, or gaseous phase, but the solution itself is not a gas.
Saturated, Unsaturated & Supersaturated Solutions: Chemistry [4]
Honey is a fascinating solution, made up of approximately 70% sugar and 20% water. Honey contains more sugars than what would normally dissolve at room temperature, and it is considered a supersaturated solution! So, if you are interested in learning about unsaturated, saturated, and supersaturated solutions, you came to the right place! This article is about saturated, unsaturated and supersaturated solutions.First, we…

Some Definitions [5]
The major component of a solution is called the solventThe major component of a solution.. The minor component of a solution is called the soluteThe minor component of a solution.
Sometimes this becomes confusing, especially with substances with very different molar masses. However, here we will confine the discussion to solutions for which the major component and the minor component are obvious.
Salt water, for example, is a solution of solid NaCl in liquid water; soda water is a solution of gaseous CO2 in liquid water, while air is a solution of a gaseous solute (O2) in a gaseous solvent (N2). In all cases, however, the overall phase of the solution is the same phase as the solvent.

Read pages 18-26 in your text book, make your own notes, focusing on the terms mentioned above. Make sure to check out the diagrams in the text as they are great for explaining some of the concepts below.
The human body is made up of more than 60 percent water by weight and it is the crucial medium for most of our critical functions. Water is also one of the few substances that can exist in all three states of matter in the rather narrow range of temperatures in which life exists.
freely, they are briefly attracted to each other as they pass by.. It takes a great deal of heat (100°C) to cause the molecules to be

If you live near a lake, a river, or an ocean, that body of water is not pure H2O but most probably a solution. Much of what we drink—for example, soda, coffee, tea, and milk are solutions
In fact, much of the chemistry that occurs in our own bodies takes place in solution, and many solutions—such as the Ringer’s lactate IV solution—are important in healthcare. In our understanding of chemistry, we need to understand a little bit about solutions
Overview, Structure, Properties & Uses [8]
Access premium articles, webinars, resources to make the best decisions for career, course, exams, scholarships, study abroad and much more with. Before we begin with the supersaturated solution, let us first have a look at ‘what is a solution?’
Those substances that get dissolved are referred to as solute and those substances in which solute is dissolved is solvent. For example, salt (solute) dissolved in water (solvent)
There is often a limit for the amount of solute that can be dissolved in a definite quantity of solvent. Especially, in cases where solids are dissolved in liquids
Supersaturation [9]
In physical chemistry, supersaturation occurs with a solution when the concentration of a solute exceeds the concentration specified by the value of solubility at equilibrium. Most commonly the term is applied to a solution of a solid in a liquid
The term can also be applied to a mixture of gases.[clarification needed]. Early studies of the phenomenon were conducted with sodium sulfate, also known as Glauber’s Salt because, unusually, the solubility of this salt in water may decrease with increasing temperature
Expanding upon this, Gay-Lussac brought attention to the kinematics of salt ions and the characteristics of the container having an impact on the supersaturation state. He was also able to expand upon the number of salts with which a supersaturated solution can be obtained
Coexistence of Different Growth Mechanisms of Sodium Chlorate under the Same Experimental Conditions [10]
Coexistence of Different Growth Mechanisms of Sodium Chlorate under the Same Experimental Conditions. Dependence of growth rates of {100} sodium chlorate crystal faces on solution supersaturation in the range of 0.44–1.32% was analyzed
The majority of the observed {100} sodium chlorate crystal faces grew in accordance with the power law R ∼ σn, whereas approximately one-third of them grew in accordance with BCF or Chernov’s theories. Possible reasons for this as well as for the coexistence of crystal faces, which grew with different mechanisms under the same conditions, have been discussed.
In an attempt to make a clear determination of the mechanism responsible for crystal growth under certain conditions, many difficulties have arisen. One of the most commonly used method to identify the growth mechanism is to study (R,σ) dependence, i.e., crystal growth rate, R, on solution supersaturation, σ, dependence.
AP Chem – 3.10 Solubility [11]
We’re back to solutions! Remember that solutions are homogeneous mixtures where the particles are evenly mixed and the solute is uniformly distributed within the solvent. The solute is the substance that is dissolved, while the solvent is the substance that does the dissolving.
dissolved in a solvent, but what does this value depend on? Let’s go over solubility!. To put it simply, solubility is the ability of a substance to dissolve in a solvent to form a homogeneous mixture
The solubility of one substance in another depends on:. Polar and ionic solutes tend to dissolve in polar solvents, and non-polar solutes tend to dissolve in non-polar solvents (remember “like dissolves like”)
Lab: Theoretical vs. Actual Yield [12]
which is the substance that gets dissolved and the solvent, the. the solute that can be dissolved under those conditions of temperature
a solution can be “tricked” into containing more solute than can. usually done by changing its conditions, such as dissolving the solid solute
Solubility is defined as the mass of solute which can be dissolved in 100. The tables below contain solubility data for two solutes, copper (II) sulfate and ammonia, in water at varying temperatures.
