it means it is dry
Neither, it is a neutral salt (conjugated with the strong acid HCl)
Sulfito estannoso
If your Group 2 cations are calcium, strontium or barium, add a solution containing sulphate ions, i.e. sulphuric acid or the sulphate of the Group I metal that is the Group I cations in your solution. The Group 2 cations will precipitate out with the sulphate ions. If you have beryllium or magnesium cations, then I don't know.
since both substance will dissolve, the barium and the sulfate will come together and barium sulfate does not dissolve in water so barium sulfate will be the precipitate.
Sodium sulphate increases the concentration of sulphate ions. So strontium sulphate solubility decreases.
No. All metal sulphate are soluble in water, except barium sulphate, calcium sulphate and lead sulphate.
No idea strontium sulphate?
it means it is dry
Copper Sulphate will dissolve better in warmer water, it will dissolve both faster and it will be possible do dissolve a greater mass of the Copper Sulphate.
Yes.
if you heat it :)
Neither, it is a neutral salt (conjugated with the strong acid HCl)
Sulfito estannoso
This is because sulphate is a thing that just dissolve in the water and changes the colour.
they dissolve or dilute
No it won’t.
