It is prepared by roasting powdered chromite with potash and limestone, treating the cinder with a hot potassium sulfate solution and leaching.
Alternatively, it may be prepared by the reaction of potassium dichromate and potassium hydroxide.

If you are given 5 gL of stock solution to make 15 ml of 2.3 gL fructose solution how many L of the stock solution is needed to make the fructose solution?
You need 6,9 mL stock solution.
What do you add to solvent to make a solution?
To make a solution, you add a solute to a solvent. The solute dissolves in the solvent, resulting in a homogeneous mixture where the solute particles are evenly distributed throughout the solvent.
A sample of 76g of NaCl is dissolved to make 1L of solution. what is the molarity of the solution?
1.3g
How many grams of EDTA do you add to make a 3.7 percent EDTA solution?
To make a 3.7% EDTA solution, you would add 3.7 grams of EDTA to 100 mL of solution.
Can you make 6 percent peroxide using 12 percent peroxide?
No, you cannot make a 6% peroxide solution by diluting a 12% peroxide solution with water. To make a 6% peroxide solution, you would need to mix equal parts of the 12% peroxide solution with water.
What is difference between K2Cr2O7 and K2Cr2O4?
K2Cr2O7 is potassium dichromate, while K2Cr2O4 is potassium chromate. K2Cr2O7 is an orange-red compound used as an oxidizing agent, while K2Cr2O4 is a yellow compound. K2Cr2O7 tends to be more powerful as an oxidizing agent compared to K2Cr2O4.
What is the oxidation number of Cr in K2Cr2O4?
The oxidation number of Cr in K2Cr2O4 is +6. This is because each oxygen atom contributes an oxidation number of -2, and each potassium atom contributes an oxidation number of +1, resulting in a total charge of 0 for the compound.
How do you make a dilute solution?
Add water to the solution
How do you make a potassium thiocynate solution?
To make a potassium thiocyanate solution, first dissolve potassium thiocyanate powder in distilled water. Stir the mixture until the powder is completely dissolved. The resulting solution can be used for various chemical reactions or experiments.
Can evaporation make a saturated solution unsaturated?
No, evaporation will most likely make the solution supersaturated
How could you make concentrated solution weaker?
A concentrated solution can be weakened by adding more of the solution material (usually water) to dilute it.
What are the values of a variable that make an equation true?
It is the solution; sometimes also called the root.
Increasing the amount of solute in a solution can make a?
concentrated solution
How can you make a super saturated solution out of a saturated solution?
You have to Heat it!
How can you make a solution?
Solute dissolves in solvent to form solution.
If you are given 5 gL of stock solution to make 15 ml of 2.3 gL fructose solution how many L of the stock solution is needed to make the fructose solution?
You need 6,9 mL stock solution.
What gets dissolved in a solution?
A solute dissolves in a solvent to make a solution
