Neutralisation Reactions

Question 1

What type of solution is sodium ethanoate

Answer 1

Alkaline

Question 2

What type of salt does weak acid strong base produce

Answer 2

Salt alkaline in solution

Question 3

What type of salt does strong acid weak base produce

Answer 3

Salt acidic in solution

Question 4

Why is standard enthalpy change of neutralisation for dilute solutions of strong acid and base always similar

Answer 4

As acids and alkalis are fully ionised in dilute solutions, produce same number of hydroxide and H+ ions

Question 5

How is standard enthalpy change of neutralisation for weak acids and bases different

Answer 5

Less negative, weak acids and bases are not fully ionised and solutions are not neutral at equivalence point and energy required to ionise
