Interpretation:
The concentration of sodium ions is to be calculated in the given solutions and the concentration of the lithium carbonate solution is to be determined.
Concept introduction:
Soluble ionic compounds dissociate completely in the solution upon dissolution, forming ions.
The compounds with
For compounds with combination other than
The molar concentrations of the species in the solution are expressed using square brackets.
