In image As a result of mineral erosion and biological activity, phosphate ion (PO,3-) is common in natural waters,where it often precipitates as insoluble salts such as Ca3(PO4)2. A researcher takes 25 ml of water fromriver #1, which has a [Ca2+] of 0.3 M, and adds it to 50 mL of water from river #2. Assume river #1contains no phosphate and that river #2 contains no calcium. What is the minimum [PO,3] in river #2 forCa3(PO4)2(9) precipitate (Kgp = 2.6 x 10º) to form in the mixed volume?

Water bodies may contains various minerals like phosphates, chlorides etc. The solubility of these…
