Question

normality and molarity questions

Answer 1

Solved ExamplesQuestion 1: Calculate the molarity of 0.650 N HCl.
Solution:Normality of HCl = 0.650N. So, it has 0.650 equivalents of HCl in 1000ml of solution.Since HCl releases only 1 proton or H+ ion in its solution, its equivalents is equal to moles.So, 0.650 equivalents = 0.650 moles in 1000cc or 1000ml.Thus, Molarity = 0.650M.

Question 2: What will be the normality of 3 molar solution of calcium hydroxide? 
Solution: 
Molarity of calcium hydroxide = 3 M.
Since calcium hydroxide releases 2 electrons in its solution, 1 mole would be equal to 1/2 equivalent.

So, its normality would be: 3232 = 1.5 normal.

So, the solution of 3M calcium hydroxide would be 1.5N.
