Use the solubility rules listed to decide if either of the ionic compounds are insoluble and will therefore form a precipitate. (i) All nitrates are soluble, so hydrogen nitrate (nitric acid) is soluble and will not form a precipitate, HNO 3 (aq). (ii) All chlorides are soluble EXCEPT those of silver, lead and mercury(I), so silver chloride is insoluble and will form a precipitate, AgCl (s)

The Brønsted–Lowry theory is an acid–base reaction theory which was proposed independently by Johannes Nicolaus Brønsted and Thomas Martin Lowry in 1923. The fundamental concept of this theory is that when an acid and a base react with each other, the acid forms its conjugate base, and the base forms its conjugate acid by exchange of a proton (the hydrogen cation, or H +).
