Answer:
Sodium hydroxide is an alkali but zinc hydroxide is a base because Sodium hydroxide is soluble in water while zinc hydroxide is insoluble in water , here both Sodium Hydroxide and Zinc Hydroxide are bases while only sodium hydroxide is alkali as bases soluble in water are known as alkali.
BASES
⋆ Bases are are substances that produce hydroxide (OH⁻) ions in aquaeous solution.
⋆ Examples of bases includes:- Sodium hydroxide (NaOH) ,Calcium hydroxide (Ca(OH)₂ ) , Magnesium hydroxide ( Mg(OH)₂ ) , etc.
ALKALIS
⋆ Alkalis are bases that are soluble in water .
⋆ Example of Alkalis include :- Sodium hydroxide (NaOH) , Potassium hydroxide(KOH) .
Extra Bite
✳ All alkalis are bases while all bases are not alkalis
