In dilute solution, the heat of reaction when acid reacts with alkali to form 1 mole of water is called neutralization heat. 1. must be a dilute solution of acid and alkali, because the concentrated acid solution and concentrated alkali solution will release heat when they are diluted with each other. 2. The dilute solution of strong acid and strong alkali can react to ensure that H+(AQ)+OH-(AQ) = = H2O (L). 3. Based on the generation of 1 mole of water.

Definition In dilute solution, the heat released by the reaction of acid and alkali to form 1 mol liquid water is called neutralization heat.

Your formula may be too conservative. Calculate q first, Q=cm△t is heat, and then divide by n.

△H=c△t(m/n) and n=m/M(M is molar mass), so both m and n are omitted, leaving m,

Your molar mass may be 25.

Q is calculated according to J. If you want to use KJ, you have to divide it by 1000, that is, Δ h = c (T2-T1)/0.025 kj/mol.

Δ h = q/n, you know, it is the heat released per mole of the system.

The definitions and points are typed in person. I hope to adopt them. ...
