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.
A chemical substance that will form a precipitate with NH4Cl solution is AgNO3, resulting in the formation of a white precipitate of AgCl. With K2CrO4 solution, Pb(NO3)2 will form a yellow precipitate of PbCrO4.
The chemical formula for potassium chromate is K2CrO4.
The dissociation equation for potassium chromate (K2CrO4) in water is: K2CrO4(s) -> 2K+(aq) + CrO4^2-(aq).
KCrO4 does not exist it is K2CrO4 and is called Potassium Chromate. Potassium dichromate is K2Cr2O7
To make a 0.25N K2CrO4 solution, you need to first calculate the molecular weight of K2CrO4 (potassium chromate). Then, determine the grams of K2CrO4 needed to make the desired volume of solution at a concentration of 0.25N. Dissolve this amount of K2CrO4 in the required volume of solvent, usually water, to make the final solution.
