Okay..What I took with my GREAT teacher
God bless him for me
The following.
Magnesium sulphate is a soluble salt so I think we should use Mg(OH)
2 (Magnesium hydroxide) not MgO ...
1)So we make titration to Mg(OH)
2 with H
2SO
4 using an indicator..
H
2SO
4+Mg(OH)
2 --> MgSo
4 +H
2O
2)repeat titration without indicator
3)heat till saturation
4)make crystillization (cooling,filtering,wash crystals with small amount of water)
