For example, if you heat the secondary alcohol propan-2-ol with sodium or potassium dichromate(VI) solution acidified with dilute sulfuric acid, propanone is formed. When aqueous solutions of potassium fluoride and nitric acid are mixed, an aqueous solution of potassium nitrate and hydrofluoric acid results. Write a balanced chemical equation for each acid-base reaction. Since the solvent is concentrated nitric acid (in which lead(II) nitrate has very low solubility) and the resulting solution contains nitrate ions, anhydrous crystals of lead(II) nitrate spontaneously form as a result of the common ion effect.
