Question

Which of the acid-base combinations below will release the most heat?

1.0 M H2SO4 + 1.0 M NaOH

1.0 M HF + 1.0 M NaOH

Answer 1

Acid - Base IM H₂SO4 Combinations + 1M NaOH 1 M HF + 1M NaoH strong acid very strong Base weak cauid Strong - Base. Neutralisation Reaction i H+ + oH HO Avanti H=-57,1KY when strong and reacts with the strong Base, the reaction is vigorous and highly enothermic, and releases Stiki of energy mole molu

A But when weak and is reacted with strong Base, then the energy released will be less than 57 1 KI as samo . mole as same amount of energy aud CHF). released is utilized to conise the weak HF - HT . Enthalpy of Cars H + oH = tf (AiH)... imisation of rom) 1 in . HF. spositive energy H, 0, -59,1K3/mote string y string Base HF positive energy + NaOH = Naf + H₂O, AH={(AIH) -57.100 L . I mole Energy released is less than -571KT so Acid-Base Combination 1M H₂SO4 + 1M Naoh release - the most heats
