Question

following pictures represent solutions of CuS, which may also contain ions other than Cu2+ and S2- which are not shown. Gray spheres represent Cu2* ions and dotted spheres represent $2-ions. 3) 33) If solution (1) is a saturated solution of Cus, which of solutions (2)-(4) are supersaturated? A) (2) C) (4) B) (3) D) none of the above Arrows in the energy diagram below represent enthalpy changes occurring in the endothermic formation of a solution: Hsoln -enthalpy of solution AHsolute-solute enthalpy change involving solute-solute interactions AHsolute-solvent enthalpy change involving solute-solvent interactions AHsolvent-solvent enthalpy change involving solvent-solvent interactions Energy 34) Which arrows represent AHsolute-solute and AHsolvent-solvent? 34) A) arrow (c) and arrow (d C) arrow (a) and arrow (t B) arrow (a) and arrow (d D) arrow (a) and arrow (c) B-7

Explanation / Answer

33) Solution 4) represents the supersaturated solution as the solution contains dotted spheres more than grey spheres which may arise because of excess addition of CuS or other components
