________ is a base that does not contain- OH.

________: an organic compound that changes color in acids and bases.

A reaction between ________ hypochlorite and ammonia produces the toxic gases hydrazine and chloramine.

________: the maximum amount of a solute that can be dissolved in a given amount of solvent at a given temperature.

________: the substance being dissolved.

________ is the process in which an ionic solid separates into its positive and negative ions.

________ also react with indicators to produce predictable changes in color.

a mixture that has the same composition, color, density, and even taste throughout

the substance being dissolved

the substance doing the dissolving

A solution in which water is the solvent

he maximum amount of a solute that can be dissolved in a given amount of solvent at a given temperature

describes how much solute is present in a solution compared to the amount of solvent

a solution that contains all the solute it can hold at a given temperature

any solution that can dissolve more solute at a given temperature

one that contains more solute than a saturated solution at the same temperature

a substance that produces hydrogen ions in a water solution

an organic compound that changes color in acids and bases

Any substance that forms hydroxide ions, OH-, in a water solution; any substance that accepts H􏰅 from acids

When it dissolves in water, almost 100 percent of the acid molecules dissociate into ions

When it dissolves in water, only a small fraction of the acid molecules dissociates into ions

dissociates completely in solution

one that does not dissociate completely

measure of the concentration of H+ ions in it

When bases that contain- ________ dissolve in water, the negative areas of nearby water molecules attract the positive ion in the base.

Some acids can damage tissue by producing ________.

________ and sports drinks are examples of solutions made by dissolving solids in liquids.

A solution with a pH of exactly 7 indicates that the ________ ions and OH- ions are equal.

Stirring a solution speeds up the dissolving process because it brings more ________ into contact with more solute.

________ behave differently from those of solids or liquids.
