Acids And Bases

Question 1

Define acid in terms of the Lowry-Brønsted model.

Answer 1

An acid is defined as a proton donor.

Question 2

Define bases in terms of the Lowry-Brønsted model.

Answer 2

A base is defined as a proton acceptor.

Question 3

Define ionisation.

Answer 3

Define ionisation as the reaction of a molecular substance with water to produce ions.

Question 4

Define a strong acid

Answer 4

Define a strong acid as an acid that ionises almost completely in an aqueous solution.

Question 5

Define weak acid

Answer 5

Define weak acid as an acid that only ionises partially in an aqueous solution.

Question 6

Define dissociation

Answer 6

Define dissociation as the splitting of an ionic compound into its ions.

Question 7

Define a strong base.

Answer 7

Define a strong base as a base that dissociates almost completely in an aqueous solution.

Question 8

Define a weak base.

Answer 8

Define a weak base as a base that only dissociates partly in an aqueous solution.

Question 9

Define an amphoteric (or amphiprotic) substance.

Answer 9

Define an amphoteric (or amphiprotic) substance as a substance that can act as either an acid or a base.

Question 10

Define a salt.

Answer 10

Define a salt as a substance in which the hydrogen of an acid has been replaced by a cation

Question 11

Define hydrolysis of a salt.

Answer 11

Define hydrolysis of a salt as a reaction with water where water itself is decomposed.

Question 12

Define neutralization.

Answer 12

Define neutralization as the point where an acid and base have reacted so neither is in excess. Also defined as the equivalence point

Question 13

Define a standard solution

Answer 13

Define a standard solution as a solution of known concentration.
