Solutions and mixtures

Collid

A colloid is a solution that has particles ranging between 1 and 1000 nanometers in diameter, yet are still able to remain evenly distributed throughout the solution. These are also known as colloidal dispersions because the substances remain dispersed and do not settle to the bottom of the container.Sep 24, 2015

Heterogeneous mixtures

A heterogeneous mixture is made of different substances that remain physically separate. Heterogeneous mixtures always have more than one phase (regions with uniform composition and properties). A mixture of sand and sugar is a heterogeneous mixture.

Rate of solution

A solute is the primary substance that is dissolved in a liquid called the solvent. So what this means is that it is when something dissolves in something else. There are many factors that affect the rate at which a solute will dissolve.

Solvent

A solvent is usually a liquid but can also be a solid or a gas.

Insoluble

An insoluble substance is a substance (solid) that will not dissolve in a solvent even after mixing (eg; sand and water).

Unsaturated solution

As the temperature of the solvent increases, solubility increases. Additionally, pressure and the nature of the solute and solvent affect solubility. When a solution can have solute added and dissolved, the solution is unsaturated.

Alloys

Brass, bronze, and steel are all alloys. A material made of two or more metals, or of a metal and another material. For example, brass is an alloy of copper and zinc; steel is an alloy of iron and carbon.

Concentrated solution

Concentrated solution is a solution that contains a large amount of solute relative to the amount that could dissolve.

Homogenous systems

Definition HS Homogeneous System. A system of linear equations, is homogeneous if the vector of constants is the zero vector, in other words,

Dilute solution

Dilution is the process of reducing the concentration of a solute in solution, usually simply by mixing with more solvent. Example 1: You can add water to concentrated orange juice to dilute it until it reaches a concentration that is pleasant to drink.

Concentration

In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration.

Solubility

Solubility is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent to form a solution of the solute in the solvent.

Supersaturated solution

Supersaturation is a state of a solution that contains more of the dissolved material than could be dissolved by the solvent under normal circumstances. It can also refer to a vapor of a compound that has a higher (partial) pressure than the vapor pressure of that compound.

Solute

The salt is the solute and the water the solvent. In chemistry, a solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.

Ways to increase the rate of solution

When the total surface area of the solute particles is increased, the solute dissolves more rapidly. Breaking a solute into smaller pieces increases its surface area and increases its rate of solution. Stirring -- With liquid and solid solutes, stirring brings fresh portions of the solvent in contact with the solute.

Solution

a homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.

Mixture

a mixture is a material system made up of two or more different substances which are mixed but are not combined chemically. A mixture refers to the physical combination of two or more substances.

Saturated solution

saturated solution is used in chemistry to define a solution in which no more solvent can be dissolved. It is understood that saturation of the solution has been achieved when any additional substance that is added results in a solid precipitate or is let off as a gas.
