What else can I help you with?
A precipitate will be formed when an aqueous carbonic acid solution is added to an aqueous solution of?
Calcium chloride. When carbonic acid is added to a solution containing calcium chloride, a white precipitate of calcium carbonate is formed due to the reaction of calcium ions with carbonate ions from carbonic acid.
What happens when sodium hydroxide is added to copper oxide the colour of precipitate?
When sodium hydroxide is added to copper oxide, a blue precipitate of copper hydroxide is formed. The color of the precipitate is due to the formation of copper ions in solution.
When a precipitation reaction occurs the ions that do not form the precipitate?
When a precipitation reaction occurs, ions that do not form the precipitate remain in the solution. These ions are called spectator ions and do not participate in the formation of the solid precipitate. They are still present in the solution, but they do not contribute to the solid formed.
What test reagent will distinguish a solube Cl- salt from So4-2?
A solution of a soluble chloride will give a white precipitate (turning purple on exposure to light) with silver nitrate solution. Sulfates do not react. Alternatively, the solution of sulfate will give a white precipitate with barium chloride solution, and the chloride solution will not.
What happens when silver nitrate is added to bromide?
When silver nitrate is added to a solution containing bromide ions, a white precipitate of silver bromide will form. This is due to a chemical reaction between the silver nitrate and bromide ions, resulting in the insoluble silver bromide precipitate.
What can be added to a solution of OH- (aq) S2- (aq) and SO42- (aq) ions to precipitate the OH- (aq) ions but not the others?
Add a solution of magnesium chloride; magnesium hydroxide is not soluble in water.
A precipitate will be formed when an aqueous carbonic acid solution is added to an aqueous solution of?
Calcium chloride. When carbonic acid is added to a solution containing calcium chloride, a white precipitate of calcium carbonate is formed due to the reaction of calcium ions with carbonate ions from carbonic acid.
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 happens when sodium hydroxide is added to copper oxide the colour of precipitate?
When sodium hydroxide is added to copper oxide, a blue precipitate of copper hydroxide is formed. The color of the precipitate is due to the formation of copper ions in solution.

What happens when silver nitrate is added to bromide?
When silver nitrate is added to a solution containing bromide ions, a white precipitate of silver bromide will form. This is due to a chemical reaction between the silver nitrate and bromide ions, resulting in the insoluble silver bromide precipitate.
What would you see when acidified silver nitrate solution is added to a solution of Low sodium salt?
When acidified silver nitrate solution is added to a solution of low sodium salt, it would form a white precipitate of silver chloride. This is due to the chloride ions in the low sodium salt reacting with the silver ions in the silver nitrate solution to form silver chloride, which is insoluble in water.
Why do you add hydrochloric acid to test for sulphate?
Hydrochloric acid is added to a solution being tested for sulphate ions to precipitate the sulphate as barium sulphate. This is a confirmatory test for the presence of sulphate ions in the solution because barium sulphate is insoluble and forms a white precipitate.
What would happen to the color of a dilute solution containing FeCl-4 if Ag plus is added?
If Ag+ is added to a dilute solution containing FeCl4-, a white precipitate of AgCl would form. This is because Ag+ ions react with Cl- ions to form AgCl, causing the color of the solution to change from the original color of the FeCl4- solution to white due to the formation of the precipitate.
Does barium sulphite precipitate when barium chloride is added to sodium sulphite solution?
Yes, barium sulfate precipitates when barium chloride is added to a sodium sulfite solution due to a double displacement reaction where barium ions from barium chloride react with sulfite ions from sodium sulfite to form a insoluble barium sulfate precipitate.
What is the test reagent for chloride ion?
Silver nitrate (AgNO3) is commonly used as the test reagent for chloride ions. When silver nitrate is added to a solution containing chloride ions, a white precipitate of silver chloride (AgCl) forms. This reaction is often used to detect the presence of chloride ions in a solution.
