How can we prepare potassium chromate?
To prepare potassium chromate, start by dissolving potassium dichromate in water and then adding potassium hydroxide to adjust the pH. The solution is then heated to evaporate water, leaving behind potassium chromate crystals. Purify the crystals by recrystallization to obtain pure potassium chromate.
What type of substance is k2cro4?
K2CrO4 is named potassium chromate. It is a salt combining mono atomic potassium cations and polyatomic chromate cations and is quite soluble in water. Its solutions in water are highly oxidizing.
What substances are formed when potassium oxide dissolves in water?
When potassium oxide (K2O) dissolves in water, it forms potassium hydroxide (KOH), which is a strong base. This reaction releases heat and is exothermic. Potassium hydroxide dissociates in water to produce potassium ions (K+) and hydroxide ions (OH-).
Why potassium iodide dissolves in water?
Potassium iodide dissolves in water due to the ionic interaction between the potassium and iodide ions with water molecules. The polar nature of water molecules allows them to surround and separate the ions in the solid potassium iodide, causing it to break apart and dissolve in water.
Will Potassium nitrate dissolves in water?
Yes, Potassium nitrate (KNO3) is highly soluble in water.

Will Potassium nitrate dissolves in water?
Yes, Potassium nitrate (KNO3) is highly soluble in water.
Is potassium phosphate water soluble?
Yes, potassium phosphate is water soluble. It dissolves readily in water, forming an aqueous solution.
When carbon dioxide dissolves in water what weak acid is prodced?
Carbonic acid is produced when carbon dioxide dissolves in water. This can then dissociate into bicarbonate and hydrogen ions in the solution.
Will the solution of potassium chloride and water conduct electricity or not explain?
Yes, a solution of potassium chloride and water will conduct electricity. When potassium chloride (an electrolyte) dissolves in water, it dissociates into potassium ions and chloride ions which can carry electric current.
Why boiling water is used instead of cold water when potassium manganate is dropped in the boiling water?
Potassium Manganate (VII) also called potassium permanganate, dissolves very quickly in hot water and much slower in cold water.
What is Constituent element of potassium sorbate?
Potassium sorbate is composed of potassium, which is inorganic, and sorbic acid, which is an organic compound. When potassium sorbate dissolves in water, it releases potassium ions and sorbate ions.
Is KSO4 soluble in water?
Yes, K2SO4 (potassium sulfate) is soluble in water. When it dissolves in water, it produces potassium ions (K+) and sulfate ions (SO4^2-).
Is K2CrO4 soluble?
Yes, potassium chromate (K2CrO4) is soluble in water. It is a salt compound that readily dissolves in aqueous solutions.
