Colloid
A mixture containing small, undissolved particles that do not settle out
Indicator
A compound that changes color when in contact with an acid or a base
Digestion
Breaks down the complex molecules of foods into smaller molecules
Solute
The substance that is present in the smallest amount & is dissolved by the solvent
Unsaturated solution
A solution in which you can dissolve more solute
Base
A substance that tastes bitter, feels slippery, and turns red litmus paper blue; produces hydroxide ions in water
Hydroxide ion
A negative ion, made of oxygen and hydrogen
Supersaturated solution
A solution that has more dissolved solute than is predicted by its solubility at the given temperature because the solution was heated
Solubility
A measure of how much solute can dissolve in a solvent at a given temperature
Neutralization
A reaction between an acid and a base
Saturated Solution
When you’ve added so much solute that no more dissolves
Solvent
The part of a solution present in the largest amount. It dissolves the other substances.
Solution
A well-mixed mixture that contains a solvent and at least one solute
Hydrogen Ion
An atom of hydrogen that has lost its electron
Corrosive
Means “eating away” at other materials
Suspension
A mixture in which particles can be seen and easily separated by settling or filtration
Acid
A substance that tastes sour, reacts with metals and carbonates, and turns blue litmus paper red; produces hydrogen ions in water
Concentrated Solution
Solution that has a lot of solute dissolved in the solvent
pH Scale
A range of values from 0 to 14 that expresses the concentration of hydrogen ions in a solution
Salt
Any ionic compound that can be made from the neutralization of an acid with a base
Dilute Solution
Mixture that has only a little solute dissolved in a certain amount of solvent
