Question

A 25.00-mL sample of an unknown HClO4 solution requires titration with 22.62 mL of 0.200 M NaOH to reach the equivalence point. What would be the concentration of NaOH in the final solution if no reaction occurs? Report your answer to three decimal places.

Answer 1

M1V1 = M2V2
M1= (0.200 mol) (22.62 mL)/ (25.00 mL)
M1 = 0.181 M
