Question
Chapter 9, Problem 79E
Interpretation Introduction
Interpretation:
“Mass of sodium phosphate is required for removal of Ca+2 and Mg+2 from a 1.5L solution” should be identified.
Concept introduction:
The phosphate ions react with Ca+2 and Mg+2 ions as:
3CaCl2 + 2Na3PO4 → Ca3(PO4)2 (s)+6NaCl
3Mg(NO3)2 + 2Na3PO4 → Mg3(PO4)2(s)+6NaNO3
Given:
Molarity of calcium chloride is 0.050M
Molarity of magnesium nitrate is 0.085M
Volume of hard water is 1.5 L
Molar mass of sodium phosphate is 163.94
