Molarity of HCl solution

20 ml of HCL solution needs 19.85 ml of 0.01M NaOH solution for complete neutralization. Morality of the HCL solution is:  (i) 0.0099 (ii) 0.099 (iii) 0.99 (iv) 9.9

Choose the right answer from above.

E

Expert

Verified

The right answer is (i)

M1V1 = M2V2
0.01 x 19.85 = M2 x  20
M2= 0.00925 : M : 0.0099
