Ignore the fa houldit be insoluble sp n phosphate is NajPO

Explanation / Answer

(1)

Adding NaCl to a saturated solution of AgCl decreases the solubility of AgCl and hence AgCl will precipitate out of solution.

(2)

For sodium phosphate, the Ksp is given by:

Ksp = [Na+]3*[PO43-] = x3*(x/3) = x4/3

Given:

x = 0.1

So,

Ksp = 0.14/3 = 0.000033
