Q. A solution of $500 \,ml$ of $0.2\, M\, KOH$ and $500 \,ml$ of 0.2 \,M $HCl$ is mixed and stirred; the rise in temperature is $T _{1} .$ The experiment is repeated using $250\, ml$ of each solution, the temperature raised is $T _{2} .$ Which of the following is true -

Thermodynamics

Solution:

$500 \,mL$ of $0.2\, M\, KOH$ (S.B.) (Use $q = mC \Delta T$)

500 of $0.2\, M\, HCl$ (S.A.)

The heat of neutralisation is same

$T _{1}= T _{2}$
