The chromate ion (CrO4^2-) generally follows these solubility rules: it is soluble in alkaline solutions and forms soluble compounds with alkali metals (like sodium and potassium) and ammonium ions (NH4+). However, chromates are generally insoluble with transition metals such as lead (Pb), barium (Ba), and calcium (Ca), which form insoluble chromate salts. Additionally, the solubility of chromates can be affected by the pH of the solution, as they tend to precipitate as insoluble forms in acidic conditions.

What is the solubility of 2-mercaptobenzimidazole?
2-mercaptobenzimidazole has limited solubility in water, but it is more soluble in organic solvents such as ethanol, methanol, and acetone. Its solubility can vary depending on the specific conditions such as temperature and pH.
For PbBr2 Ksp equals 6.3 x 10-6 at 25C What is the solubility of PbBr2 at this temperature?
The solubility of PbBr2 at 25°C can be calculated using the Ksp value. Since PbBr2 dissociates into Pb2+ and 2 Br- ions, the solubility (S) can be found using the expression Ksp = [Pb2+][Br-]^2. By substituting the given Ksp value into the equation, you can solve for the solubility of PbBr2 at 25°C.
Write the solubility product expression for silver chromate.?
The solubility product expression for silver chromate (Ag2CrO4) is Ksp = [Ag+]²[CrO4²-], where [Ag+] represents the concentration of silver ions and [CrO4²-] represents the concentration of chromate ions in the saturated solution.
