LiOH

Answer 1

Arrhenius bases: NaOH, KOH and LiOH.

Step-by-step explanation:

Arrhenius bases are hydroxide (
`OH^(-)`) containing molecules which furnish
`OH^(-)` ion in aqueous solution.

So, clearly, NaOH, KOH and LiOH are arrhenius bases as they contain
`OH^(-)` ion as well as furnish
`OH^(-)` ion in aqueous solution.

Hydrolysis in water:
`NaOH(S)+H_(2)O(l)\rightarrow Na_(aq.)^(+)+OH_(aq.)^(-)`

`KOH(S)+H_(2)O(l)\rightarrow K_(aq.)^(+)+OH_(aq.)^(-)`

`LiOH(S)+H_(2)O(l)\rightarrow Li_(aq.)^(+)+OH_(aq.)^(-)`
