The titration of 17.20 mL of HCl solution of unknown concentration requires 12.53 mL of a 0.170 M NaOH solution to reach the equivalence point. What is the concentration of the unknown HCl solution in M?

Respuesta :

Answer:

0.233m

Explanation:

c1/v1=c2/v2

c1/17.20= 0.17/12.53

hence c1= 0.17x17.2/12.53

therefore c1=0.. 233M
