We have learned about strong bases and weak bases. Which of the following bases would be considered weak?
- sodium fluoride
- ammonia
- potassium hydroxide
- calcium hydroxide
- none of the above



Answer :

Answer:

Ammonia (NH3) is the weak base.

  • Sodium fluoride (NaF) and potassium hydroxide (KOH) are both strong bases.
  • Calcium hydroxide (Ca(OH)2) is a strong base, but its solubility in water is limited.  

Ammonia is a weak base because it only partially ionizes in water to produce hydroxide ions.
