Answer 5

Insoluble

Question 6

Titration method

Answer 6

1. Soluble

2. Sodium, potassium and ammonium

Question 7

Precipitation method

Answer 7

Has to be insoluble

Question 8

Excess base/metal method

Answer 8

1. Soluble

2. Not sodium, potassium or ammonium

Question 9

Describe precipitation method

Answer 9

1. Mix two solutions containing the ions that you need
2. Salt is obtained by filtering the mixture
3. Wash salt and leave to dry

Question 10

Describe excess base/ metal method

Answer 10

1. Pick an avid and an I soluble base
2. Add base to acid. You will know if it has neutralised as the excess base will not dissolve
3. Filter out the excess and evaporate the water to get crystals
