Manufacture of acids and bases<\/h3>\n\n\n\n

a) Nonmetal oxide + water \u2192 acid<\/p>\n\n\n\n

SO2<\/sub>(g) + H2<\/sub>O(l) \u2192 H2<\/sub>SO3<\/sub>(aq)
SO3<\/sub>(g) + H2<\/sub>O(l) \u2192 H2<\/sub>SO4<\/sub>(aq)
4NO2<\/sub>(g) + 2H2<\/sub>O(l) + O2<\/sub>(g) \u2192 4HNO3<\/sub>(aq)<\/p>\n\n\n\n

Non-metal oxides are thus referred to as acid anhydrides.<\/p>\n\n\n\n

b) Hydrogen + halogen \u2192 acid<\/p>\n\n\n\n

H2<\/sub>(g) + Cl2<\/sub>(g) \u2192 2HCl(g)
HCl(g) + H2<\/sub>O(l) \u2192 HCl(aq)<\/p>\n\n\n\n

c) Metallic salt + conc. sulphuric acid \u2192 salt + more volatile acid
2NaCl(aq) + H2<\/sub>SO4<\/sub>(aq) \u2192 Na2<\/sub>SO4<\/sub>(aq) + 2HCl(aq)
2KNO3<\/sub>(aq) + H2<\/sub>SO4<\/sub>(aq) \u2192 K2<\/sub>SO4<\/sub>(aq) + 2HNO3<\/sub>(aq)<\/p>\n\n\n\n

d) Metal + oxygen \u2192 metallic oxide (base)
4Na(s) + O2<\/sub>(g) \u2192 2Na2<\/sub>O(s)
2Mg(s) + O2<\/sub>(g) \u2192 2MgO(s)<\/p>\n\n\n\n

e) Metal + water \u2192 base or alkali + hydrogen
Zn(s) + H2<\/sub>O(steam) \u2192 ZnO(s)+ H2<\/sub>(g)<\/p>\n\n\n\n

f) Few metallic oxides + water \u2192 alkali
Na2<\/sub>O(s) + H2<\/sub>O(l) \u2192 2NaOH(aq)<\/p>\n\n\n\n

g) Ammonia + water \u2192 ammonium hydroxide
