When calcium ions (Ca²⁺) and sulfate ions (SO₄²⁻) in water combine, they form calcium sulfate (CaSO₄), which is mostly insoluble and precipitates out of the water. This precipitation can be seen when a solution containing calcium ions and sulfate ions is mixed together, resulting in the formation of a solid calcium sulfate precipitate.
You need to provide the other reactants. There are several reactions that can theoretically produce calcium sulfide.

What 2 starting compounds you can use to precipitate calcium sulphate?
You can use calcium chloride and sodium sulfate as starting compounds to precipitate calcium sulfate. Mixing these two solutions will result in the formation of calcium sulfate precipitate.
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 reaction of calcium hydroxide and sulfuric acid forms calcium sulfate and water, while the reaction of sodium hydroxide and sulfuric acid forms sodium sulfate and water. These differences occur because of the different chemical properties of calcium and sodium, leading to the formation of different products during the reactions.
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.
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.
In a reaction between sodium sulfate and calcium chloride what is the name of the precipitate formed and what colour is it?
The precipitate formed is calcium sulfate, which is a white solid.
What 2 starting compounds you can use to precipitate calcium sulphate?
You can use calcium chloride and sodium sulfate as starting compounds to precipitate calcium sulfate. Mixing these two solutions will result in the formation of calcium sulfate precipitate.
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.
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.
Why is the reaction of calcium hydroxide and sulfuric acid different from sodium hydroxide and sulfuric acid?
The reaction of calcium hydroxide and sulfuric acid forms calcium sulfate and water, while the reaction of sodium hydroxide and sulfuric acid forms sodium sulfate and water. These differences occur because of the different chemical properties of calcium and sodium, leading to the formation of different products during the reactions.

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.
What is the percent of water in calcium sulfate?
Calcium sulfate, also known as gypsum, typically contains about 20% water by weight.
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.
Is calcium sulfate hcl insoluble?
Calcium sulfate is generally insoluble in water, meaning it does not readily dissolve in water. However, the solubility of calcium sulfate can be affected by factors such as temperature and the presence of other chemicals.
