Paper 1 - Making Salts + Acids

Question 1

How can we make soluble salts?

Answer 1

Soluble salts can be created by mixing an acid with an insoluble reactant

Question 2

What three insoluble reactants can you add to acids to make salts?

Answer 2

You could add metals / metal oxide / carbonate to make salts with acids

Question 3

How do you name salts?

Answer 3

The first part of salts will be the name of the insoluble reactant eg zinc oxide. The second part of salts will be the name of the acid eg hydrochloric acid = chloride

Question 4

Copper Oxide + Nitric acid =

Answer 4

Copper nitrate

Question 5

What is the name of the salt that comes from hydrochloric acid?

Answer 5

Hydrochloric acid = Chloride

Question 6

What is the name of the salt that comes from nitric acid?

Answer 6

Nitric acid = Nitrate

Question 7

What is the name of the salt that comes from sulfuric acid?

Answer 7

Sulfuric acid = Sulfate

Question 8

What is the method of making a soluble salt (4 steps) :

Answer 8

1) . Add acid to a beaker
2) . Add insoluble reactant to the beaker, stirring the mix
3) . Continue to add insoluble reactant until it is in excess
4) . Filter the mix in the beaker to remove excess reactant

Question 9

Why would you add the salt in excess when making soluble salts?

Answer 9

The salts are in excess so all of the acid is reacted as otherwise it will contaminate the salt and become dangerously contaminsated
