okay, the solubility is affected by temperature.  However, in this problem, we have data for the solubility at that temperature.

cooltowl · Answer

Is there a specific equation that I can go by? Just wondering?

The first thing you need to do is write the equation for the dissolution of lithium carbonate in aqueous solution.

$$\text{Li}_2\text{CO}_3\text{(s)}\rightarrow  2 \text{Li}^{+}\text{(aq)} +\text{CO}_3^{2-}\text{(aq)}$$

Does This have to do with the ICE chart?
