Given:
Volume of Nitric acid(V₁) = 100 ml
Normality(N₁) = 1 N
Normality after dilution(N₂) = 0.1 N
To find:
The volume of water needed to dilute the solution
Calculation:
We know the formula
N₁V₁ = N₂V₂
By substituting the given values in the above formula
1×100 = 0.1×V₂
V₂ = 100×10
V₂ = 1000 ml
Final volume of the solution is 1000 ml
Volume of water = 1000 - Volume os nitric acid
= 1000 - 100
= 900 ml
Final answer:
The volume of water needed to dilute the solution is 900 ml [Option(a)]
