Question. 40

40. Fill in the missing data in the following table

Name of the saltFormulaSalt obtained from — BaseSalt obtained from — Acid
(i) Ammonium chlorideNH₄ClNH₄OH—
(ii) Copper sulphate——H₂SO₄
(iii) Sodium chlorideNaClNaOH—
(iv) Magnesium nitrateMg(NO₃)₂—HNO₃
(v) Potassium sulphateK₂SO₄——
(vi) Calcium nitrateCa(NO₃)₂Ca(OH)₂HNO₃

Answer:

(i) Ammonium chloride — Formula: \(\mathrm{NH_4Cl}\); Base: \(\mathrm{NH_4OH}\); Acid: \(\mathrm{HCl}\).
(ii) Copper sulphate — Formula: \(\mathrm{CuSO_4}\); Base: \(\mathrm{Cu(OH)_2}\); Acid: \(\mathrm{H_2SO_4}\).
(iii) Sodium chloride — Formula: \(\mathrm{NaCl}\); Base: \(\mathrm{NaOH}\); Acid: \(\mathrm{HCl}\).
(iv) Magnesium nitrate — Formula: \(\mathrm{Mg(NO_3)_2}\); Base: \(\mathrm{Mg(OH)_2}\); Acid: \(\mathrm{HNO_3}\).
(v) Potassium sulphate — Formula: \(\mathrm{K_2SO_4}\); Base: \(\mathrm{KOH}\); Acid: \(\mathrm{H_2SO_4}\).
(vi) Calcium nitrate — Formula: \(\mathrm{Ca(NO_3)_2}\); Base: \(\mathrm{Ca(OH)_2}\); Acid: \(\mathrm{HNO_3}\).

Detailed Answer with Explanation:

Steps: Table entries filled by identifying salt formulae and the typical base/acid from which they are formed (salt = base + acid neutralisation).
