Acids / Bases Foster ESS Study this for the Quiz
Acid Acid- substances produced by hydrogen ions. Comes from Latin word acidius which means “sour”
Bases A substance that produces OH ions in solution or accepts hydrogen ions Bases taste bitter Bases feel slippery Strong bases are very dangerous and can burn your skin
When acids and bases are added to each other they react to neutralize each other if an equal number of hydrogen and hydroxide ions are present. Acid + Base = a salt and Water The scientific name for the reaction is called neutralization.
