4500 kg/h of a solution that is 1/3 K2CrO4 by mass is joined by a recycle stream containing 36.4 % K2Cr04, and the combined stream is fed into an evaporator. The concentrated stream leaving the evaporator contains 49.4% K2CrO4, and is in turn fed into a crystallizer in which it is cooled. The cooling causes crystals of K2CrO4 to precipitate.

Question: Balance the following equation: K2CrO4 + Na2SO3 + HCl-KCl + Na2SO4 + CrCl3 + H2O Generally coefficients of 1 are omitted from balanced chemical equations. When entering your answer, include coefficients of 1 as required for grading purposes.

Apr 14, 2015 · $\ce{K2Cr2O7}$ is red-yellow and $\ce{K2CrO4}$ is bright yellow. I am leaning towards the fact that due to the increased amount of bond pairs in $\ce{K2Cr2O7}$ it becomes harder to remove the d orbital electron and that causes the light emitted to be of a higher wavelength (lower frequency) and that's why there is colour difference.

Sep 26, 2014 · Definitely you need to remember it. Potassium Chromate is IUPAC name of $\ce{K2CrO4}$. There are other names such as Chromic acid and dipotassium salts. But mostly IUPAC names are accepted. I don't think you should try to mug up all 24 names instead you should keep getting familiar with them when they come in reactions or somewhere else.

A stock solution of K2CrO4 is available to prepare solutions that are more dilute. Calculate the volume, in mL, of a 2.0-M solution of K2CrO4 required to prepare exactly 100 mL of a 0.570-M solution of K2CrO4.

K2CrO4+Na2SO3+HCl→KCl+Na2SO4+CrCl3+H2O. Generally coefficients of 1 are omitted from balanced chemical equations. When entering your answer, include coefficients of 1 as required for grading purposes. Enter the coefficients for each compound, separated by commas, in the order in which they appear in the equation (e.g., 1,2,3,4,5,6,7).
