I am doing an entropy lab and my lab group is using NH4Cl (s) and H2O (l) to make an endothermic reaction. I need to know the products of the reaction
People have different answers:
NH3 + HCl + H2O
NH4+ + Cl-
NH4OH + HCl
I know that according to solubility rules, NH4Cl deionizes.
NH4Cl + H2O -> ?
Thanks for any help given.
What you are doing is not really an endothermic reaction but rather a "heat of solution" lab. When you dissolve NH4Cl in water you get a solution of NH4+ and Cl- ions in water and a large amount of energy is absorbed when the NH4Cl dissolves. So basically you have the ammonium chloride solid dissociating in water to form positive and negative ions.
