What causes salt to dissolve in ethanol? And what type of reaction is this

Answer 1

Salt dissolves in ethanol because ethanol is a polar solvent, meaning it has a positive and negative end that can attract and interact with the positively and negatively charged ions in the salt. When salt is added to ethanol, the polar molecules of ethanol surround and separate the ions in the salt, causing it to dissolve.

This is a physical reaction, specifically a dissolution or solvation process.
