i) Titration is used for soluble Group(I) or ammonium salts, since potassium is an element from Group(I) and is also soluble titration is used to prepare its salt.
ii) Normal Equation: 2
Ionic Equation: 2OH- (aq) + H+2 ---> 2H20 (L)

Question 4.
Q4 Sulfuric acid is titrated with potassium hydroxide in the preparation of potassium sulfate salt. (i) Explain why this method is recommended for the preparation for this salt. (ii) Write an ionic equation for the reaction.

ii) Normal Equation: 2K+OH- (aq) + H+2SO4²⁻(aq) ---> K2+SO4²⁻(aq) + 2H20 (L)
Ionic Equation: 2OH- (aq) + H+2 ---> 2H20 (L)
