5. Find the pH and % hydrolysis of 0.1 M NaNO2 Na+ is the salt of a strong base (NaOH) and NO 2 – is the salt of a weak acid (HNO 2). Therefore this salt will make the solution basic. Aug 15, 2013 · Thus we may also speak of strong acids or bases, and weak acids or bases. Neutral molecules such as acetic acid and ammonia are examples of weak electrolytes. All metal salts formed from reaction of strong acids and strong bases are themselves strong electrolytes. Such a salt may be very insoluble, meaning that very little of it dissolves in water.

Nitric acid is a strong acid and a very powerful oxidizing agent. It oxidizes almost all metals it comes in contact with, except gold and platinum. Unlike the reactions of metals with other strong acid (such as HCl and H2SO4), the reactions of nitric acid with metals do not produce H2 gas. Examples of strong acids are hydrochloric acid (HCl), perchloric acid (HClO4), nitric acid (HNO3) and sulfuric acid (H2SO4). A weak acid is only partially dissociated, with both the undissociated acid and its dissociation products being present, in solution, in equilibrium with each other.
