Question

Hello,

I was wondering what would happen if u add KOH(potassium hydroxide) solution instead of KOH solid to HCL (hydrochloric acid).

Currently, learning enthalpy in class and I'm not sure how this affects enthalpy

Answer 1

When using solid KOH, the volume of the solution doesn't change significantly and delta T will be some value. When adding a solution of KOH, the volume of the KOH will add to that of the HCl; therefore, the heat generated must heat a larger about of water and delta T will be somewhat smaller.
