Question

What is the normality of a solution in which 2.0 g of ca(oh)2 is dissolved in 1.0 l of solution

Answer 1

Answer:

Normality(N)= (given mass ×n factor)÷ (molar mass ×vol (litre) of sol.)

♡given mass=2

♡molar mass=40+(16+1)2= 74

♡volume=1 (litre)

♡ n factor =2 as it give two OH ion

☆ N= 2×2÷ 74 × 1= 0.05
