Zinc salts cause a milky turbidity in water in higher concentrations. Additionally, zinc may add an unwanted flavour to water. This occurs at concentrations of about 2 mg Zn 2+ / L. Solubility of zinc and zinc compounds. The solubility of zinc depends on temperature and pH of the water in question. When the pH is fairly neutral, zinc in water ...
