hi! this is my first time to be here.
would anyone be kind enough to explain to me why a weak acid is usually less negative than for strong acids and bases? My answer is: because weak acids are not completely ionized in the solution, energy has to be used to break down the bond between the H+ ions and A- ions. Hence, the amount of energy released in the reaction, i.e. the heats of neutralization, becomes smaller. Am I getting into the wrong way?
Besides, I don't understand why experimental results for hydrochloric acid are usually a little less negative than -57.6 kJmol-1, while the others are not. (That's what my teacher told me, without explanation.) Should they be the same?
Please *delete me* Thank you!
