Question

help me solve these two please

O Rank the following substances in order of inceaning molar Solubility ( – smallest molar solubility ; S=largest Imolar solubility) in water at 25°C Ballz Ksp=4.0x/0-7 Balott), Ksp=s.oxl03 Ksp = 7.9x10 to Ksp = 8.9810-12 ksp= 2.5 X10-10 SoFz Mg(OH)2 CuCO3 @ For the aqueous [Hg (NH3)4]? complex has a Ke stes xlo" at 25°C Suppose equal volumes of 0.0082 m Hg(NO3)2 Solution and 0.72 m Nhz Solution were mixed Calculate the equilibrium concentration (M aqueous Hight ion 2+ LOR

Answer 1

+ (03 Ane BacO₂ 7- Boat S S S? 4X10-9 Sa J4x10-9 9 s= 6:32 x 10-5 Воон), Beat + 2OH s as Ksp a (s ) [as]? 453 = Ksp 43 : 5 X10-3 3 Sz 1.25 X10 5 = 1:07 X10' 100 con get the ideo about sslubility The order will be Cu CO₂ Cu + (OP- S S نهم 25 XIO 1 s. 1:58*10S CS Scanned with CamScanner

we can get the idea of solubility Lowest » Cu (03 BaCO3 - Mg(OH)₂ う Sc Fa BaOH)2 CS Scanned with CamScanner

Please like the answer if you find it helpful. I did the best I could.
