Question

Calculate the concentration (in molarity) of NaOH solution if 25.0mL of the solution are needed to neutralize 17.4 mL of a 0.132M HCL solution

Answer 1

Given:

25.0mL NaOH
17.4 mL of a 0.132M HCL

Required:

molarity of NaOH

Solution:

M1V1 = M2V2

(25.0mL) M1 = (0.132 M HCl)( 17.4 mL)

M1 = 0.092 M NaOH

V1 = 0.5 liters
