How is an acid prepared from a non metal and a base from a metal? Give equation.
Acid from a non metal:
Certain non metals like sulphur (S), phosphorous(P), can be oxidized by concentrated nitric acid to yield corresponding acid.
Non metal + Acid → Acid + water + Oxide
S + 6HNO3 → H2SO4 + 2H2O + 6NO2
Base from a metal :
Active metals like K, Na, Ca react with water to produce water soluble bases. These bases are called alkalis.
Active metal + water → Base/Alkali + Hydrogen
2Na + 2H2O → 2NaOH + H2.
