if you added 3.2652 g of calcium chloride to your diluted sodium phosphate solution what reaction would occur?

Solutions

Expert Solution

Both salts are water-soluble, and after mixing together, they undergo a double-displacement reaction, and they form sodium chloride, which is soluble and remains in solution, and calcium phosphate, which is not soluble in water and precipitates out of solution. The balanced reaction equation can be given as:

2Na3PO4       +     3CaCl2            →           6NaCl        +        Ca3(PO4)2 (precipitate)

327.88 g              332.94 g                        351.0 g                      310.17 g (precipitate)

As from balanced equation:

332.94 g of CaCl2 gives --------- 310.17 g of Ca3(PO4)2 as precipitate

Then 3.2652 g of CaCl2 will gives------3.2652 X 310.17 / 332.94

= 1012.767084 / 332.94 g of Ca3(PO4)2 as precipitate

= 3.041 g Ca3(PO4)2 as precipitate

Sodium phosphate is added to a solution that contains 0.0099 M aluminum nitrate and 0.021 M calcium chloride. The concentration of the first ion to precipitate (either Al3+ or Ca2+) decreases as its precipitate forms. What is the concentration of this ion when the second ion begins to precipitate? Hint: Note that well over 99% of the first ion has precipitated before the second ion starts to precipitate. Correct Answer: 2.613e-7 (I need an "EXPERT" to show me how to...
