Extracted text: 1. a. Calcium intake is crucial among infant and children. For children with calcium deficiencies, calcium phosphate or calcium carbonate supplements are commonly prescribed to aid healthy teeth and bone development. i. If the molar solubility of Ca3(PO4)2 is 2.56 x 105 M, calculate its solubility product. ii. A nutritionist prepares calcium carbonate solution by mixing equal volume of 2.5 x 10s M Ca(NO3)2 and 3.4 x 10s M NazCO3. Given that the Ksp of CaCO3 is 8.7 x 10º, determine whether the solution is saturated, supersaturated, or unsaturated.
