a water soluble compound that donates protons (H+ ions) to a base, These are often sour in taste, can burn the skin and eyes, and react with a base to produce salt and water. These are corrosive to metals. All have hydrogen in them.

compound formed from (+) ion from the base (metal) and the (-) ion from the acid

corrosion reaction

single replacement
acid + metal --> salt + H2 (gas)

neutralization reaction

double replacement
acid + base --> salt + water

being or containing an acid
have pH values less than 7

being or containing a base
have a pH value greater than 7

a water-soluble chemical compound that accepts protons from an acid. These are often bitter in taste, have a slippery texture, and react with acids to produce salt and water. The chemical formula for these usually end in OH.

a substance that changes color when in contact with an acid or a base

neither acidic nor basic
pure water

a measure of how many hydrogen ions there are in a solution. The greater the number of hydrogen ions, the more acidic the solution. The symbol stands for "potential hydrogen" or "power of hydrogen"
