AKS 6: Solutions, Solubility, & pH

Solute

• A substance that is dissolved in a solution.

• A liquid that dissolves a solute.

• A mixture of two or more substances.

• A solid that cannot dissolve in any liquid.

Surface Area

• The measure of how much exposed area a solid object has, affecting the rate of dissolution.

• The total volume of a solid object.

• The weight of a solid object when submerged in water.

• The temperature at which a solid object melts.

litmus paper

• a type of paper used for writing notes

• a pH indicator that changes color when it comes into contact with an acid or a base

• a paper used for filtering liquids

• a type of paper that measures temperature

Pressure

• The force exerted by the substance per unit area on another substance, affecting solubility.

• The amount of matter in a given volume of space.

• The temperature at which a substance changes from solid to liquid.

• The speed at which a substance moves through a medium.

Unsaturation

• A state of a solution where more solute can be dissolved.

• A state of a solution where no more solute can be dissolved.

• A state of a solution that contains only one solute.

• A state of a solution that is saturated with solute.

Solution

• A heterogeneous mixture of different substances.

• A homogeneous mixture composed of two or more substances.

• A pure substance with a uniform composition.

• A mixture that cannot be separated by physical means.

Solubility

• The ability of a substance to dissolve in a solvent to form a homogeneous mixture.

• The measure of how much solute can be dissolved in a solvent at a given temperature.

• The process of separating a mixture into its individual components.

• The ability of a substance to remain solid at high temperatures.

pH

• stands for 'potential of hydrogen' and is a measure of how acidic or alkaline a solution is

• is a measure of the temperature of a solution

• is a scale that measures the density of a solution

• is a term used to describe the color of a solution

Temperature

• A measure of the average kinetic energy of the particles in a sample of matter, affecting the rate of dissolution.

• The total amount of heat energy in a substance.

• The degree of hotness or coldness measured on a specific scale.

• The energy required to change a substance from solid to liquid.

Saturation

• The state of a solution in which no more solute can dissolve at a given temperature and pressure.

• The process of adding more solute to a solution until it becomes cloudy.

• The maximum amount of solute that can be dissolved in a solvent at any temperature.

• A condition where a solution has an excess of solute that precipitates out.
