Title: What chemicals react to produce calcium sulphate and magnesium carbonate?
Post by: hxha5 on 12/05/2020 05:10:27
Hello, I need the answers for the reactants of the following insoluble salts:

Calcium Sulphate

Magnesium Carbonate

The question isn't really clear. Are you asking what chemicals react together to product those two chemicals?

Yes

Trying to remember my distant chemistry lessons...if you want to know which compounds are soluble in water, producing an insoluble residue, read the solubility rules...
Quote from: The Solubility Rules
#2. All sodium, potassium, and ammonium salts are soluble in water
#3. The chlorides, bromides, and iodides of (most) metals ... are soluble in water.
Use Rule #2: Select a Sodium salt: Sodium Sulphate and Sodium Carbonate.
Use Rule #3: Select a Chloride salt: Magnesium Chloride and Calcium Chloride

Sodium Sulphate(aq) + Calcium Chloride(aq) = Calcium Sulphate(s) + Sodium Chloride (aq)

Sodium Carbonate(aq) + Magnesium Chloride(aq) = Magnesium Carbonate(s) + Sodium Chloride(aq)

Or copper sulphate and calcium acetate
or ammonium sulphate and calcium nitrate or
magnesium sulphate and calcium iodide
sulphuric acid and calcium chloride
or lots and lots of other possible combinations.
There's no single answer to the question.
Essentially, almost any soluble sulphate and any soluble calcium salt

CaO + SO3 → CaSO4

2 Mg + 3 CO2 → 2 MgCO3 + C

Mg (OH)2 + Mg(HCO3)2  --> 2 MgCO3  +H2O

MgC2 +CO2 + H2O  --->  C2H2 +MgCO3

There's a similar one for the other carbide.

Calcium sulfate is not produced, but can be occurred in Gypsum !
