Acids and Bases

Chemical Reactions

Acids

bases (products: salt and water)

metals (products: salt and hydrogen), Exception 1: dil. nitric acid reacts with reactive metals produces salt, nitrogen dioxide and water instead of salt and hydrogen, Exception 2: un-reactive metals such as copper, silver and gold do not react with acids

metal carbonates (products: salt, carbon dioxide and water)

Alkalis

acids (products: salt and water)

ammonium salts (product: salt, ammonia and water

salt (product: metal hydroxides and new salt), For identification of cations (QA)

Oxides

metal oxides

basic oxides, oxides of all metals except ZAP, behave like bases. Have reactions typical of bases

amphoteric oxides, ZAP (zinc, aluminium and lead(II) oxides), can behave as base or acid. Have reactions with acids and bases

non metal oxides

acidic oxides, oxides of all non metal except those that are neutral oxides, behave like acids. Have reactions typical of acids

neutral oxides, CO, NO, H2O, does not behave as acid or base. No reaction with acids and bases

pH

pH = 7

neutral

conc. hydrogen ions = conc. hydroxide ions

pH = 1

very strongly acidic, strong acids dissociate completely in water to give high conc. hydrogen ions

conc. hydrogen ions much higher than conc. hydroxide ions

pH = 14

very strongly alkaline, strong alkalis dissociate completely in water to give high conc. hydroxide ions

conc. hydrogen ions much lower than conc. hydroxide ions

Properties

Acids

sour

pH<7

conduct electricity, strong acids conduct better because complete dissociation of acid molecules lead to higher concentration of hydrogen ions

Bases

bitter taste

slippery feel

pH>7

soluble bases conduct electricity, strong alkalis conduct better because complete dissociation of alkali molecules lead to higher concentration of hydroxide ions
