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.

Potassium sulfate is a group (I) salt, colourless and soluble. Titration method is for group (I) and ammonium salt. Therefore, the salt can be prepared using titration method

ii)Write an ionic equation for the reaction.

2H+ (aq) + OH- (aq) à H2O
