WebFeb 28, 2014 · M AV A = M BV B. Let's assume you are titrating a strong acid (10 mL unknown concentration HCl) with a strong base (1.0 M NaOH). It takes 25mL of NaOH to neutralize the acid. If you solve for M A you will see that. M A = ( M BV B) / V A. or M A = (1.0M x 25mL) / 10. M A = 2.5M HCl.
