Question | Answer |
---|---|
a well mixed mixture that contains a solvent and at least one solute | solution |
the part of a solution present in the largest amount that dissolves the other substance | solvent |
the substance that is present in a solution in a smaller amount and is being dissolved | solute |
a mixture containing small, undissolved particles that do not settle out | colloid |
a mixture in which particles can be seen easily separated by settling or filtration | suspension |
mixture that has only a little solute in a certain amount of solvent | dilute solution |
a measure of how much solute can dissolve in a solvent at a given temperature | solubility |
when so much solute is added to a solution so that no more dissolves | saturated solution |
when you can continue to dissolve more solute in the solution | unsaturated solution |
a solution that has more dissolved solute than is predicted by its solubility at the given temperature | supersaturated solution |
a substance that tastes sour, reacts with metals and carbonates, and turns blue litmus paper red | acid |
“eat away” other materials | corrosive |
a compound that changes color when in contact with an acid or base | indicator |
a substance that tastes bitter, feels slippery, and turns red litmus paper blue | base |
a range of values from 0-14 that expresses the concentration of hydrogen ions in a solution | pH scale |
a mixture that has a lot of solute in the solvent | concentrated solution |
an atom of hydrogen that has lost its electron | hydrogen ion |
a negative ion made of oxygen and hydrogen | hydroxide ion |
a reaction between an acid and a base | neutralization |
any ionic compound that can be made from the neutralization of an acid with a base | salt |
the process of breaking down large food molecules into smaller molecules | digestion |
a physical process in which large pieces of food are torn and ground into smaller pieces | mechanical digestion |
breaks large molecules into smaller ones by chemical means | chemical digestion |
