Answer 1

Answer #1

Answer:-

This question is solved by firstly calculating the concentration of lead and chromate ions in the solution then Qsp is calculated and compared with Ksp.

The answer is given in the image,

2: [Pb2+] = 3.0x10*55.0 x10-6 M (68092] = 1.0x104°= 5.0X10-41 M Gsp=[Pb2+7 (68092-] Asp= (5.0x106) (5-0X1041) Qsp= 2.5x10-16
