Conclusions:
1.
Calculate the average value for the Ksp of lithium carbonate at 20°C.
2.
Use a reference book or on-line sources to find the actual Ksp of lithium carbonate.
3.
Calculate the % error of your calculated Ksp of lithium carbonate.
4.
Discuss possible sources of error that would account for a discrepancy of greater than 10%.
Questions:
1. If the concentration of [Li*] were doubled (say, by adding a highly soluble Li salt such as Lil), what
would be the new concentration of [CO32] in the saturated solution?
2. If the concentration of [CO32] were doubled (say, by adding a highly soluble carbonate salt such as
Cs₂CO3), what would be the new concentration of [Li] in the saturated solution? Why is the effect
less than in question 1?
