Question

According to the Arrhenius theory, when a base
dissolves in water it produces
(1) CO3 2– as the only negative ion in solution
(2) OH– as the only negative ion in solution
(3) NH4 + as the only positive ion in solution
(4) H+ as the only positive ion in solution

Answer 1

According to Arrhenius Theory of acids and bases, when a base dissolves in water, the only negative ion produced is OH-.

Therefore, (2) OH– as the only negative ion in solution is the correct answer.

Hope this would help~
