When potassium chromate dissolves in water what ions are produced?
When potassium chromate dissolves in water, it produces potassium ions (K⁺) and chromate ions (CrO₄²⁻).
What do ammonia and acid make?
Ammonium ions: NH3 + H+ --> NH4+
What acid neutralises ammonium hydroxide to make ammonium chloride?
Hydrochloric acid (HCl) can neutralize ammonium hydroxide (NH4OH) to form ammonium chloride (NH4Cl) and water. The reaction involves the H+ ions from the acid reacting with the OH− ions from the base to form water, while the remaining ions combine to form the salt.
What is the pH of ammonium formate?
The pH of a 0.1 M solution of ammonium formate is approximately 6.0. This is because when ammonium formate dissolves in water, it undergoes hydrolysis to form ammonium ions and formate ions. The presence of these ions affects the pH of the solution.
How many ions in silver chromate?
Two types: silver (Ag+) and chromate (CrO4-2) And within the formula (Ag2CrO4) there are two silver ions and one chromate ion for a total of three ions.
Ammonium chromate formula?
The formula for ammonium chromate is (NH4)2CrO4. It consists of two ammonium ions (NH4+) and one chromate ion (CrO4^2-), with a 2:1 ratio between the two ions.
Choose the correct formula for a compound between ammonium and chromate ions?
The correct formula for a compound between ammonium and chromate ions is (NH4)2CrO4. The ammonium ion is (NH4)+ and the chromate ion is (CrO4)2-.
When potassium chromate dissolves in water what ions are produced?
When potassium chromate dissolves in water, it produces potassium ions (K⁺) and chromate ions (CrO₄²⁻).

How chromate ions are converted into dichromate ions?
In an acidic solution chromate ions are converted into dichromate ions.
Does water dissolve ammonia?
Yes, ammonia dissolves in water to form ammonium ions NH4+ or ammonium hydroxide NH4OH Yes, ammonia dissolves in water to form ammonium ions NH4+ or ammonium hydroxide NH4OH
What do ammonia and acid make?

Why is lead chromate not soluble in water?
Lead chromate has a low solubility in water due to the strong electrostatic forces between the lead and chromate ions, which hold the compound together in a solid form. These forces prevent the ions from separating and dissolving in water, resulting in poor solubility.
Is ammonium carbonate an insoluble salt?
yes Ammonium carbonate is soluble in water.
