2014年9月26日 · 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.

2015年4月14日 · $\ce{K2Cr2O7}$ 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.
