It has low tinting strength and opacity. 0000004548 00000 n In the first two examples, we show how barium and strontium can be separated as chromate. 0000086541 00000 n What is Ksp in chemistry? It is a conjugate of chromic acid. A mixture of metal ions in a solution can be separated by precipitation with anions such as \(\ce{Cl-}\), \(\ce{Br-}\), \(\ce{SO4^2-}\), \(\ce{CO3^2-}\), \(\ce{S^2-}\), \(\ce{Cr2O4^2-}\), \(\ce{PO4^2-}\), \(\ce{OH-}\) etc.
