Practice question · Sort into groups
Sort each species by its behaviour in water.
Groups: Strong acid · Weak acid · Strong base
- Potassium hydroxide
- Hydrochloric acid
- Acetic acid
- Carbonic acid
- Sodium hydroxide
- Nitric acid
Hints
- Strong means essentially complete ionisation, not merely corrosive.
- The organic and carbonic acids ionise only partially.
Show the answer
Strong acid: Hydrochloric acid, Nitric acid
Weak acid: Acetic acid, Carbonic acid
Strong base: Sodium hydroxide, Potassium hydroxide
Why
Hydrochloric and nitric acids ionise essentially completely; acetic and carbonic acids only partially; the group 1 hydroxides dissociate completely as strong bases.

- A 0.1 M solution of acetic acid has pH 2.9 while 0.1 M hydrochloric acid has pH 1. What does this show?
- Pure water undergoes autoprotolysis, and the equilibrium constant Kw increases with temperature. What follows…
- A solution has pOH = 4.5 at 25 °C. Compute its pH.
- A concentrated solution of a weak acid can have a lower pH than a dilute solution of a strong acid.
- Match each acid to its conjugate base.
- Why is the chloride ion unable to raise the pH of a solution?
