What else can I help you with?
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 is the reaction of potassium chromate with barium sulphate?
When potassium chromate reacts with barium sulfate, a precipitation reaction occurs. Barium chromate is formed as a yellow precipitate, while potassium sulfate remains in solution. This reaction can be used to detect the presence of sulfate ions in a solution.
Is potassium chromate a cation?
No, Potassium chromate is a compound
How do you make Copper II Chromate?
Copper(II) chromate can be prepared by reacting a solution of sodium chromate with a solution of copper(II) sulfate. The resulting precipitate is then filtered and dried to obtain solid copper(II) chromate.
How many moles of silver chromate will be formed when a silver nitrate solution of known concentration is added to a specified volume of potassium chromate solution of the same concentration?
The number of moles of silver chromate formed will depend on the stoichiometry of the reaction between silver nitrate and potassium chromate. You need to know the balanced chemical equation, as well as the exact volumes and concentrations of the silver nitrate and potassium chromate solutions to calculate the number of moles of silver chromate formed.
What is the name of this formula k2CrO4?
KCrO4 does not exist it is K2CrO4 and is called Potassium Chromate. Potassium dichromate is K2Cr2O7
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 happened when potassium chromate solution was poured to the lead nitrate solution?
A bright yellow precipitate of lead chromate forms when potassium chromate solution is added to lead nitrate solution. This is due to the exchange of ions between the two solutions, resulting in the insoluble compound lead chromate being formed.
Solutions of lead nitrate and potassium dichromate are mixed.?
A double displacement reaction will occur, forming solid lead(II) chromate and soluble potassium nitrate. Lead(II) chromate is a yellow precipitate, while potassium nitrate remains in solution.
How do you prepare 0.1N potassium permanganate?
To prepare 0.1N potassium permanganate solution, dissolve 3.16 grams of potassium permanganate in 1 liter of water. This will give you a solution with a normality of 0.1N.
Is there any way to make lead chromate?
by the reaction of lead nitrate with potassium chromate or potassium dichromate
What Calculate mass of potassium chloride required to prepare its 40 solution in 100g of water?
To prepare a 40% potassium chloride solution in 100g of water, you would need to calculate the mass of potassium chloride required. Since the solution is 40% potassium chloride, that means 40g of the total solution mass must be potassium chloride. Therefore, you would need to add 40g of potassium chloride to the 100g of water to prepare the solution.
