: During Water Softening Treatment Mg2 Ions Can Be Precipitated Out By Increasing The Ph Forming Mg Oh 2 If The Initia 1 (27.41 KiB) Viewed 59 times

During water softening treatment, Mg2+ ions can be precipitated out by increasing the pH, forming Mg(OH)2. If the initial [Mg2+] is 3.37 x 10-3 M, to what must the pH be raised to precipitate out 90.0 % of the initial [Mg²+]? The Ksp for Mg(OH)2(s) is 4.22 x 10-12.
