Question 7

Making insoluble salt / precipitation reaction method

Answer 7

1. Add1 spatula of soluble salt (lead nitrate) to test tube + add water to dissolve it ( use deoinsed water so no unwanted ions affect results)
   
   • Shake thoroughly - all dissolved
   • Repeat with other soluble salt (magnesium suldate)
2. Tip the 2 solutions into small beaker and stir to make sure all mixed
3. filter out the precipitate(lead sulfate) that forms into conical flask
4. swill out beaker with more deoinised water and tip into filter paper - to get all precipitate from beaker
5. rinse cotent of filter paper with distilled water to make sure all soluble magnesium nitrate has been washed away
6. Leave in an oven / on radiator to dry

Question 8

Precipitate -

Answer 8

An insoluble solid produced from 2 aqueous solution (soluble)
