12.7 neutralisation reactions

Question 1

what are approximate values of neutralisation reactions between strong acids & alkalis?

Answer 1

-56 to -58 kJ/mol

Question 2

what is the general equation of reacting a strong acid & alkali?

Answer 2

H+ + OH- -> H2O

Question 3

how is the enthalpy change of neutralisation of weak acids compared to strong acids?

Answer 3

less exothermic
-> energy absorbed to ionise acid & break the bond to the H in undissociated acid

Question 4

which acid-base combination gives an alkaline salt in solution?

Answer 4

weak acid & strong base

Question 5

which acid-base combination gives an acidic salt in solution?

Answer 5

strong acid & weak base
