What else can I help you with?
What 2 starting compounds you can use to precipitate calcium sulphate?
Epsom salt (magnesium sulfate heptahydrate) and calcium chloride (sold as DampRid).
Is CaSO4 Precipitate?
Yes, CaSO4 (calcium sulfate) can form a precipitate when soluble calcium and sulfate ions combine in a solution. This usually occurs when the solubility limit of CaSO4 is exceeded, causing it to come out of solution and form a solid precipitate.
Why is the reaction of calcium hydroxide and sulfuric acid different from sodium hydroxide and sulfuric acid?
The reactions of sodium hydroxide and calcium hydroxide with sulfuric acid will produce sodium sulfate and calcium sulfate respectively (water will be another product in both reactions. Sodium sulfate is soluble in water and so will remain in solution. Calcium sulfate, however, is insoluble and will precipitate as a solid.
Is calcium sulfate soluble in water?
Yes, calcium sulfate is sparingly soluble in water.
Which type of salt crystallizes from sea water first calcium sulfate or sodium chloride and why?
Calcium sulfate (gypsum) would typically crystallize from sea water first due to its lower solubility compared to sodium chloride (table salt). As sea water evaporates, the concentration of calcium sulfate increases until it reaches its saturation point and begins to precipitate out as crystals. Sodium chloride, being more soluble, would crystallize at a later stage of evaporation.
In a reaction between sodium sulfate and calcium chloride what is the name of the precipitate formed and what colour is it?
the precipitate is calcium sulfate (CaSO4) and its white in color

Barium sulfate plus calcium chloride?
When barium sulfate is mixed with calcium chloride, a double displacement reaction occurs where barium chloride and calcium sulfate are formed. Barium chloride is soluble in water, while calcium sulfate is not, so a solid precipitate of calcium sulfate will form.
What happens when you mix Calcium Chloride with Copper Sulfate?
When calcium chloride is mixed with copper sulfate, a white precipitate of calcium sulfate forms due to the displacement reaction between calcium and copper ions. This reaction is a double displacement reaction in which calcium sulfate and copper chloride are formed.

What is the percent of water in calcium sulfate?
Calcium sulfate, also known as gypsum, typically contains about 20% water by weight.
What precipitate is formed with MgSO4 and AgNO3?
A white precipitate of silver sulfate (Ag2SO4) is formed when magnesium sulfate (MgSO4) reacts with silver nitrate (AgNO3) due to the insolubility of silver sulfate in water.
Is calcium sulfate is a soluble substance?
Calcium sulfate has a very low solubility in water.
Does barium acetate and lithium sulfate form a precipitate?
Yes, when barium acetate and lithium sulfate are mixed, a white precipitate of barium sulfate would form due to a double displacement reaction. This is because barium sulfate is insoluble in water.
