1. Comment on the effect a variation from these assumptions will have on the solubility of calcium carbonate
a. the pH of the buffer does not remain at its set point but drifts lower upon dissolution of calcium carbonate.
b. The temperature in the lab is either higher or lower than 25degrees celcius as assumed in our constants in our data table.
c. The CO2 level in the lab is higher or lower than that assumed in our constants in our data table.
2. Why do you think we need to convert the calcium carbonate to calcium chloride befoe we do our EDTA titrations? What specific condition in our titrations require this?
