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

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.
