QUICK ANSWER

The temperature of the solution will increase by

2

∘

C

regardless of how much strong acid and strong base you're mixing because the enthalpy change of neutralization,

Δ

H

neut

, is constant at constant pressure.

Basically, when you increase the quantities of strong acid and strong base that you're mixing, the heat given off and the volume of the resulting solution will increase by the same factor.

more acid + base

The reaction will give off more heat, but there will be more of the resulting solution to heat, so you will end up with

Answer 2

1) 0.6° C

2°/15=X/5

x=10/15=0.66666

round it to 0.6°C
