Manipal MET2014ChemistrySome Basic Concepts of Chemistry
An aqueous solution of phosphoric acid, H ₃ PO ₄ being titrated has molarity equal to 0.25 M . Which of the following could be normality of this solution?
Options
- A0.25 N
- B0.50 N
- C0.75 N
- DAll of these
Correct answer
D. All of these
Step-by-step solution
As phosphoric acid is a tribasic acid, its n -factor can be 1, 2 or 3 . Hence, its normality can be M , 2 M or 3 M , Where, M is molarity of solution. Therefore, N=0.25,0.50 or 0.75 .
