PbCrO4
Lead ions = Pb2+Chromate ions = CrO4-2Compound they form is Lead(II) chromate = PbCrO4
Pb(CrO3)2
(NH4)2CrO4
Cr2CrO43 is not a correct chemical formula. If you meant Cr2(CrO4)3, it would indicate a compound with two chromium atoms and three chromate ions. Chromate ions have a charge of -2 each, so the compound would have a charge of 6- in total.
The compound formed between aluminum ions (Al^3+) and phosphate ions (PO4^3-) is aluminum phosphate, with the formula AlPO4.
The chemical formula of lead chromate is PbCrO4.
Lead ions = Pb2+Chromate ions = CrO4-2Compound they form is Lead(II) chromate = PbCrO4
Lead ions = Pb2+Chromate ions = CrO4-2Compound they form is Lead(II) chromate = PbCrO4
(NH4)2CrO4
Cesium chromate is the ionic compound with the formula Cs2CrO4. It is composed of cesium ions (Cs+) and chromate ions (CrO42-), which are held together by ionic bonds.
Pb(CrO3)2
(NH4)2CrO4
Calcium chloride is the compound formed by calcium ions and chloride ions. Its chemical formula is CaCl2.
When ammonium and chromate ions form a reaction, ammonium chromate is produced. Ammonium chromate is a yellow-orange solid compound that is typically used in analytical chemistry and as a chemical reagent.
KCl
The compound formed between aluminum ions (Al^3+) and phosphate ions (PO4^3-) is aluminum phosphate, with the formula AlPO4.
The compound formed by Na+ and PO43- ions is sodium phosphate, which has the chemical formula Na3PO4.
