Consider a solution that contains just 0.535 grams of ammonium chloride in 200. mL of water (recall that ammonium is the conjugate acid to the base ammonia, NH3): a. Write an equilbrium reaction for the dissolution of aqueous ammonium chloride. b. Based on your knowledge of the solubility of ammonium salts, would the equilibrium constant for part "a" be much larger than 1, much smaller than 1, or about 1? c. Based on your answer to part "b", what chemical species are present in solution after the dissolution equilibrium is established?
