Question

d)Write the steps in deducing the chemical formula of potassium nitrate.
Ans:​

Answer 1

Explanation:

Sodium sulphate contains Na+ cation & (SO4)2- anion, thus molecular formula of sodium sulphate is Na2SO4.

Potassium nitrate contains K+ cation & (NO3)- anion, thus molecular formula of potassium nitrate is KNO3.
