Question

20 ml of hcl solution required 19.8 5 ml of 0.01 molar any word solution for complete neutralization the molarity of hcl solution is

Answer 1

Answer: The molarity of HCl solution will be 0.0099M.

Explanation:

The equation used for the neutralization reaction for an acid and base is given as:

$M_1V_1=M_2V_2$

where,

$M_1\text{ and }V_1$ are the molarity and volume of acid which is HCl.

$M_2\text{ and }V_2$ are the molarity and volume of base.

We are given:

$M_1=?M\\V_1=20mL\\M_2=0.01M\\V_2=19.85mL$

Putting values in above equation, we get:

$M_1\times 20=0.01\times 19.85\\\\M_1=0.0099M$

Hence, the molarity of HCl solution will be 0.0099M.
