What else can I help you with?
Did the evidence in the silver nitrate tests of the three solutions prove conclusively that he residue actually was potassium chloride?
Yes, the silver nitrate test is a confirmatory test for chloride ions, which react with silver ions to form a white precipitate of silver chloride. Therefore, if the silver nitrate test produced a white precipitate in all three solutions, it provides strong evidence that the residue was indeed potassium chloride.
Can potassium chloride be prepared from zinc and hydrogen chloride?
No, reacting zinc with hydrogen chloride will yield zinc chloride and hydrogen gas. Potassium chloride can be prepared by reacting potassium with hydrogen chloride or (more safely) potassium hydroxide with hydrogen chloride.
What yields potassium hydroxide hydrogen?
"Potassium hydroxide hydrogen" is meaningless.
Hydrochloric acid plus what makes potassium chloride plus water?
When hydrochloric acid reacts with potassium hydroxide, potassium chloride and water are produced. This is a neutralization reaction that forms a salt (potassium chloride) and water as the products.
How many grams of potassium chloride are formed by the decomposition of excess potassium chlorate to yield 3.40 L of oxygen?
To determine the grams of potassium chloride formed, you first need to calculate the moles of oxygen produced by the decomposition of potassium chlorate. Then, use the stoichiometry of the balanced chemical equation to convert moles of oxygen to moles of potassium chloride. Finally, from the molar mass of potassium chloride, you can calculate the grams formed.
Mercuric chloride and potassium iodide?
When mercuric chloride is mixed with potassium iodide, a white precipitate of mercuric iodide is formed. This reaction is a double displacement reaction where the ions in the two compounds switch partners. Mercury(II) chloride is soluble in water, while potassium iodide is also soluble, so their reaction forms the insoluble mercuric iodide precipitate.
Why potassium carbonate cannot be prepared by solvay process?
Potassium carbonate cannot be prepared by the Solvay process because potassium salts are highly soluble in water, making it difficult to separate potassium carbonate from the solution produced in the process. The Solvay process is specifically designed for the production of sodium carbonate, which has different solubility properties compared to potassium carbonate.

In a double displacement reaction between calcium nitrate and sodium carbonate the precipitate produced would be?
Since it is a double displacement and the products of the reaction would be sodium nitrate and calcium carbonate, the precipitate would be calcium carbonate. This is because this reaction is a solubility based reaction, and sodium nitrate is a soluble compound (every metal is soluble in nitrate, and sodium dissolves in almost everything too). Whereas calcium carbonate is insoluble, and therefore will remain solid and form the precipitate.
What yields potassium hydroxide hydrogen?
"Potassium hydroxide hydrogen" is meaningless.
What salt is produced mixing barium carbonate and hydrochloric acid?
BaCl2; Barium chloride.
What is the precipitate produced in the bromination reaction?
There need to be more details provided to answer this question. If you are referring to the white precipitate that is produced in the bromination of phenol which is also known as phenylamine by adding bromine(aq) to phenol or phenylamine then the answer is 2,4,6-tribromophenol or it can be written as 2,4,6-tribromophenylamine.
Hydrochloric acid plus what makes potassium chloride plus water?
When hydrochloric acid reacts with potassium hydroxide, potassium chloride and water are produced. This is a neutralization reaction that forms a salt (potassium chloride) and water as the products.
What is made when iron sulphate and sodium carbonate are mixed?
When iron sulfate and sodium carbonate are mixed, iron carbonate and sodium sulfate are produced. Iron carbonate is a solid precipitate that can be formed during the reaction, while sodium sulfate remains in solution.
What is the formula of the blue solid material produced in the reaction of cooper (ii) nitrate with potassium carbonate?
This is the basic copper carbonate - Cu2(OH)2CO3.
