Academic Physical Science - Chapter 23: Acids, Bases, and Salts

acid

any substance that produces hydrogen ions in a water solution

hydronium ion

ions that forms which an acid dissolves in water and hydrogen ions interact with water

indicator

organic compound that changes color in acids and bases

base

any substance that forms hydroxide ions in a water solution

strong acid

any acid that dissociates almost completely in solution

weak acid

any acid that only partly dissociates in solution

strong base

any base that dissociates completely in solution

weak base

any base that does not dissociate completely in solution

pH

a measure of the concentration of hydronium ions in a solution using a scale ranging from 0 to 14, with 0 being the most acidic and 14 being the most basic

buffer

solution containing ions that react with added acids or bases and minimize their effects on pH

neutralization

chemical reaction that occurs when the hydronium ions from an acid react with the hydroxide ions from a base to produce water molecules

salt

compound formed when negative ions from an acid combine with positive ions from a base

titration

process in which a solution of known concentration is used to determine the concentration of another solution

soap

organic salts with nonpolar, hydrocarbon ends that interact with oils and dirt and polar end that helps them dissolve in water
