An 11.5 mL portion of 0.162 M H3PO4 (aq) is to be titrated with 0.229 M NaOH (aq). What volume (in mL) of NaOH will it take to reach the equivalence point

8.14 mL of NaOH are required to reach the equivalence point.

Explanation:

Formula for titration is

mmoles of base = mmoles of acid.

Equality is fullfilled at the equivalence point.

M of acid . volume of acid = M of base . volume of base

Let's replace with data given:

11.5 mL . 0.162M = 0.229 M . volume of base

Volume of base = (11.5 mL . 0.162M ) / 0.229M

Volume of base = 8.14 mL

8.14 mL of NaOH are required to reach the equivalence point.

answer: your mm
