Which is the best tool to find the volume of the base that she needs to neutralize the acid

The best tool to find the volume of the base taht she needs to neutralize the acid is M1V1 = M2V2. an example is given below.

Given:

12.0 M HCl

2.0 liters of a 3.0 M HCl

Required:

volume of concentrated hydrochloric acid

Solution:

M1V1 = M2V2

(12.0 M HCl) V1 = (3.0 M HCl) (2.0 liters)

V1 = (3.0 M HCl) (2.0 liters) / (12.0 M HCl)

V1 = 0.5 liters
