Oxidizing Zinc - Paste Metal Polish
Oxidizing Zinc The color of zinc may be changed by immersing the zinc in a mixture of 100 parts sulphuric acid, 100 parts nitric acid, and common salt 1 per cent. After remaining a little while in the mixture it acquires a dead lustre; this will become a bright one if the object is plunged in several times, and rinsed as often, in the same compound.
Explain why calcium sulfate is less soluble in sodium …
The solubility of calcium sulphate compared to sodium sulphate has to be explained. Concept introduction: When the concentration of one of the ions of a chemical solution got higher, it reacts with counter charged ions and precipitated out as salt till the ion product equals solubility product is called common ion effect.

University of Zinc Chloride, Pure n USP BP Manufacturers
Zinc enolates, prepared from alkali metal enolates and ZnCl2, provide control of stereochemistry in aldol condensation reactions due to chelation on to the zinc. This is because the chelate is more stable when the bulky phenyl group is pseudo-equatorial rather than pseudo-axial, i.e., threo rather than erythro.
