Personal precautions, protective equipment and emergency proceduresUse personal protective equipment. Potassium chromate is added a small amount at a time to first precipitate $\ce{BaCrO4}$. Bismuth and antimony salts hydrolyze in water to give basic salts. (1) Express the solubility in units of grams per liter. 0000064895 00000 n 0000074928 00000 n What is the Ksp value at this temperature?
