This depends on what the metal cation is. If the metal cation is a transition metal ion then it would be coloured, like in the case of FeSO4 which is blue/green. Many sulfates are soluble and if there is excess solvent no precipitate would be observed.

Will a precipitate form if solutions of potassium sulfate and barium nitrate are combined?
Yes, a precipitate of barium sulfate will form because barium ions (Ba²⁺) from barium nitrate react with sulfate ions (SO₄²⁻) from potassium sulfate to form an insoluble compound, barium sulfate (BaSO₄). This insoluble compound will precipitate out of solution.
What is the test for barium ions?
The test for barium ions involves adding a solution of a sulfate compound (e.g. sodium sulfate) to a solution containing the barium ions. A white precipitate of barium sulfate forms if barium ions are present.
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.
Why is Barium Sulphate used in the limit test for sulphates?
Barium sulfate is used in the limit test for sulphates because it forms a highly insoluble precipitate with sulfate ions. This property allows for the qualitative or quantitative determination of sulfate ions in a sample by measuring the amount of barium sulfate precipitate formed. The formation of a white precipitate confirms the presence of sulfate ions in the sample.
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.
Will a precipitate form if solutions of potassium sulfate and barium nitrate are combined?
Yes, a precipitate of barium sulfate will form because barium ions (Ba²⁺) from barium nitrate react with sulfate ions (SO₄²⁻) from potassium sulfate to form an insoluble compound, barium sulfate (BaSO₄). This insoluble compound will precipitate out of solution.
What is the precipitating agent used to precipitate sulfate?
Barium chloride is commonly used as a precipitating agent to precipitate sulfate ions as insoluble barium sulfate. This reaction is often utilized in analytical chemistry to detect the presence of sulfate ions in a solution.
What is the test for barium ions?
The test for barium ions involves adding a solution of a sulfate compound (e.g. sodium sulfate) to a solution containing the barium ions. A white precipitate of barium sulfate forms if barium ions are present.
What precipitate is produced when aluminum sulfate and barium chloride react?
When aluminum sulfate and barium chloride react, the precipitate formed is barium sulfate (BaSO4). This is because barium sulfate is insoluble in water, leading to its precipitation upon mixing with the two solutions.
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.
Why is Barium Sulphate used in the limit test for sulphates?
Barium sulfate is used in the limit test for sulphates because it forms a highly insoluble precipitate with sulfate ions. This property allows for the qualitative or quantitative determination of sulfate ions in a sample by measuring the amount of barium sulfate precipitate formed. The formation of a white precipitate confirms the presence of sulfate ions in the sample.
Is the solution of epsom salts prepared by dissolving magnesium sulfate heptahydrate in water is added to a solution containing sodium lauryl sulfate will a precipitate form?
Yes, a precipitate may form because magnesium sulfate heptahydrate contains magnesium ions which can react with the sulfate ions from sodium lauryl sulfate to form insoluble magnesium sulfate. This reaction can result in the formation of a white precipitate.
Does hydrochloric acid form a precipitate with cupric sulfate solution?
No, hydrochloric acid does not form a precipitate with cupric sulfate solution because chloride ions remain in solution and do not react with copper ions to form a solid product.
Calcium sulfate will precipitate in water?
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.
What are the spectator ions in silver sulfate plus barium nitrate reaction?
The spectator ions in the reaction between silver sulfate and barium nitrate are nitrate (NO3-) ions and sulfate (SO4^2-) ions. These ions do not participate in the formation of the precipitate (barium sulfate) and remain unchanged throughout the reaction.
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 do you add to Pb2 and Ba2 the lead will precipitate?
By adding sulfate ions (SO4^2-) to a solution containing Pb^2+ and Ba^2+, lead sulfate (PbSO4) will precipitate due to its low solubility product. Barium sulfate (BaSO4) will also precipitate, as it is also insoluble in water.
