Question

Calculate the solubility at

25°C

of

NiOH2

in pure water and in a

0.0120M

NaOH

solution.

Answer 1

KAP, Ni Cong) 6.0x1016 Ni Lox) u Nize (all 4208 & S 25 - KAP= (Nize). (on)2 - 6.0x10th - (3). (2572 = 5.31x106m [s in the motor solubility] In 0.012 M Naon. Ја , Sat -РОИ on = Naon - 0.012 Ni Cona Niztcap) & 2000 s 25+0.012 (due to Naoy of kap ix very leps, so 25+0.012 u 0.012

198= (3). (0.0122 = 6.0x10th = (5) (0.012)2 s= 4.17X 1012 M
