Question
Calcium citrate (Ca(C₂H₂Oh MM 498.46 g/mol), a common food preservative, has a K of 1.12 x 10¹5 at 25°C.
A. Write the reaction equation for the dissolution of Ca,(CH₂O) solid (in your solution sheet).
B. Calculate the solubility in mg/L at 25 C in pure water. Neglect other competing equilibria.
C Calculate the solubility in mg/L at 25 C in the presence of 0.010 M CaCl, Neglect other competing equilibria
Assume that 3s<<0.010 M.
D. Is the assumption that s<<0,010 M valid? (Yes or No)
