making salts practical

Question 1

what is neutralisation

Answer 1

a chemical reaction between an acid and a base in which a salt and water are formed

Question 2

what is filtration

Answer 2

a seperation technique used to remove an insoluble substance from a solution

Question 3

what is evaporation

Answer 3

a seperation technique used to remove water from a solution

Question 4

what is crystallisation

Answer 4

a technique that follows evaporation in which crystals form

Question 5

why is insoluble base added in excess

Answer 5

to make sure that all of the acid has reacted and is neutralised
