Acids, Bases and Salts Flashcards
define what is an acid?
an acid is a proton donor.
what is an acid anhydride?
an acid anhydride is a compound that reacts with water to form an acid
define a base?
a base is a proton acceptor
define an alkali?
an alkali is a base which dissolves in water to form a solution that contains OH- ions
define a salt?
a salt is a compound formed when some or all of the hydrogen ions in an acid are replaced by metal or ammonium ions
what is acidic and basic?
Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic.
what is a basic oxide?
basic oxides are oxides of some metals which react with both acids and strong alkalis to form a salt and water.
what is an acidic oxide?
acidic oxides are oxides of some non-metals which react with alkalis to form a salt and water
what are amphoteric oxides?
amphoteric oxides are oxides of some non non-metals which do not react with acids or alkalis
what are neutral oxides?
neutral oxides are oxides of some non-metals which do not react with acids or alkalis
what is a strong acid?
a strong acid is an acid that is completely ionized in water
what is a weak acid?
a weak acid is an acid that is partially ionized in water
what are acid reactions?
acid + metal = salt + hydrogen
acid+ base + salt + water
acid + metal carbonate/ hydrocarbonate= salt + water + carbondioxide

Ascorbic acid/ Vitamin C- C6H8O6
Citric acid- C6H8O7
lactic acid- C3H6O3
ethanoic acid- CH3COOH
what do bases include?
