Witryna24 gru 2024 · Is Koh a strong or a weak base? Salts of Strong Acids and Strong Bases When nitric acid is combined with potassium hydroxide potassium nitrate is formed: K+ is the conjugate acid of the strong base KOH. NO3- is the conjugate base of the strong acid HNO3. A very weak acid or base will not affect the pH of an aqueous solution. Witryna24 sie 2024 · C5H5NH + ( aq) + H2O ( l) ⇀ ↽ − C5H5NH ( aq) + H3O + ( aq) Equation 16.9.1 indicates that H3O + is a stronger acid than either NH + 4 or C5H5NH +, and conversely, ammonia and pyridine are both stronger bases than water. The equilibrium will therefore lie far to the left in both cases, favoring the weaker acid–base pair.
