Answer 1

Solution 1. Ciren, Molar solubility of mercury (1) sulfate (2) = 5.7 x 10²4. Ksp of (My soy) = Hege soy > 2ugt & soup Al quilibrim – 2. Ksp - (28) s - 463 – 4X (5.7 x 10-73 - 740.77 x 10-9 2 s kop. = 4.40x1077

Bire, Motorstwo Ksp of salt calcium hydroxide (Calom), ) = 1.3x10 het Molar solubility of calcium hydrovrede - * Calon ? Cant + 200 25 At eg who inn We know, Ksp - s. (25) ² 1.3x100 = 453 s- 1.3x100 - 350.325 x 10- 1-3X10 30.325 XID 6 = 0.687x10 - 2M Is - 0.00687 M

have Cruiser, We have saturated solution of culor And we be to tell if the following species are added to cu fort, they will affect its solubility or not To a) Cusoy is added Solesility decreases) . which when added • Cusoy contains thet as a common in with custo in to Culoin, to the concentration of cultion will potentially increase in the solution to minimise this, the equlibriun will shift to the backwed direction ic it will lead to the had more formation of Culon sting Therefore ultimately the solubility of the Cu Con will decrease Culor Cult t on sentent Cu soy & Curt & so y²- qulebonim will stift to the backward direction since the cu2t concentration has increased according to Le-chatelies Principle

bling is added - No effect] LiNo, does not contain to Culon, so it will not and species or uon common effect the solubility. c) Har is added HBr is added - No effect] Hor also does not contain any species or in Common to Culon, so it will not effect the solubility. al 4 0.0000000844 M. birn, ksp of Ins= 2.3x10-11 Concentration of the soy to it was added solution t oooory of = 8.44 xloem and Male Kep Masoy & Tritel 8.44X10M Malt & soy - (- R.yuxio PM 7:44 X10-RM + Atequlibrium Mas Mit & 5 k sp= 2.3x10-13 At qulibruin Ksp = [sh24] [5] 2.3% 10-11 = 8.44 x 10-MXs - S - 2-3x10 844 X 10-8 S 0-27 x 10-5 M
therefore molar solublity of MnS = 0.27*10^-5 M
