I'm having a problem with a base question:

Which of the following is an Arrhenius base?

A. HClO
B. HBrO2
C. Li2CO3
D. HNO2

Arrhenius base yields OH, but how do you know which one will yield an OH?

Li2CO3 + 2H2O====> 2 (Li+ + OH-)+ H2CO3

In this case were looking for weak arrhenius bases ( dont have OH- anion). The 2Li dissociates in water leaving a co3 (-2) anion. This anion reacts with 2 water molecules and takes one H+ from each H2O. leaving you with H2CO3 and 2OH-. *reiteration of dannys explanantion*
