15.00 mL of 0.100 M NaOH is required to completely neutralize 25.00 mL of an HCl solution. What is the concentration of the HCl solution? Select one: a. 0.0600 M b. 0.100 M c. 0.167 M d. 1.50 M

Answer

a. 0.0600 M

Explanation

15.00 mL of 0.100 M NaOH is required to completely neutralize 25.00 mL of an HCl solution. What is the concentration of the HCl solution?

Formula = M1V1 = M2V2

M1 = 0.100 M

V1 = 15 mL

M2 = ?

V2 = 25 mL

0.1 * 15 = M2 * 25

M2 = 0.1 * 15 / 25

M2 = 0.06 M

The concentration of HCl solution is 0.06 M
