Consider the following reaction equation: 2HCl+Ca(OH)2CaCl2+H2O. What is the volume of 0.1moldm3 HCl that would completely neutralize 25cm3 of 0.3moldm3 Ca(OH)2?

A.

150cm3

B.

75cm3

C.

30cm3

D.

25cm3

Correct answer is A

Using the formula, CAVACBVB=NANB, we have

0.1×VA0.3×25=21

VA=0.3×25×20.1×1

VA=150cm3
