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 else can I help you with?
What is the charge for CrO4?
The charge for CrO4 is 2-. This is because the oxygens in the molecule each have a charge of 2-, so the overall charge is balanced by the chromium having a charge of 2+.
What is the formula for chromate and phosphate?
The chemical formula for chromate is CrO4^2- and for phosphate is PO4^3-.
Strychnine solubility in water?
Strychnine solubility in water is 0,02 % at 20 oC.
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.
What is the central atom hybridization of CrO4 2-?
In the chromate ion (CrO4²⁻), the central chromium (Cr) atom undergoes sp³ hybridization. This is because chromium is bonded to four oxygen atoms through sigma bonds, resulting in a tetrahedral geometry. The hybridization allows for the distribution of electron density around the chromium atom to accommodate the four oxygens effectively.
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.
Is Pb(CrO4)2 a molecular compound?
No. It is an ionic compound composed of the lead IV cation (Pb4+) and the chromate anion (CrO4)2-.Pb4+ + 2(CrO4)2- --> Pb(CrO4)2
