Question

why weak acid called alkalies?

Answer 1

Ammonium hydroxide can either exist as NH3 and H2O or as NH4+ and OH- through a reversible reaction. When ammonium hydroxide is allowed to reach equilibrium, far more NH3 and H2O exists compared to NH4+ and OH-, so the concentration of OH- is low and hence ammonium hydroxide is considered to be a weak alkali.

Answer 2

weak acid are called alkalies because:-

• due to less concentration of hydrogen ions.
• due to low Ph value .
