Question

Potassium sulphate can be prepared by the reaction between dilute sulphuric acid and
potassium carbonate.
H 2 SO 4 + K 2 CO 3 → K 2 SO 4 + CO 2 + H 2 O
Calculate the mass of potassium sulphate that can be prepared from 3.45 g of potassium
carbonate.

Potassium hydrogen carbonate reacts with dilute sulphuric acid to form potassium sulphate, carbon dioxide and water.

Answer 2

Answer:

138g K2CO3 forms 174g K2SO4

So, 3.45g of K2CO3 will form = 174/138 × 3.45 = 4.35g of K2SO4
