identify neutralisation as a proton
transfer reaction which is
exothermic

 

[KFunk]

HCl + NaOH -----> H₂O + NaCl
i.e
H⁺ + Cl^- + Na⁺ + OH^- ---> H₂O + Cl^- + Na⁺

You'll notice that an H⁺ ion is being transfered which combines with the OH^- creating that neutralisation effect. An H⁺ ion is simply a proton which is why neutralisation can be considered a proton transfer reaction.

The neutralisation reaction H⁺ + OH^- ---> H₂O is exothermic where ΔH = -56 Jmol^-1 (or some amount like that)

wat kfunk said, all identify dot pts are, are for students to understand that statement ie. that a neutralisation reaction involves a proton transfer (H+ ion) and it is exothermic (releases heat)

 

[richz]

The neutralisation reaction H⁺ + OH^- ---> H₂O is endothermic where ΔH = -56 Jmol^-1 (or some amount like that)

by the way do you mean exothermic??

 

[KFunk]

Yes, yes I do I'll just change that, well spotted.

Exo Thermic!

by the way do you mean exothermic??

Exo means giving out thermic means heat in latin I guess
All neaturalisation reactions are exorthrmic reactions
Exorthermic reactions are the reactions where heat is given out
always exothermic reactions can be identified by a neagtive enthalphy value.

exo is outside in greek ;D
