1. Consider an aqueous separation that is saturated with nitrogen gas and sugar (glucose) at 80 °C. You may restrainteclosure from exhortation that as restraint most non-ionic solutes, Ks restraint glucose increases with increasing clime. Restraint N2, as restraint most gases, KH decreases with increasing clime. Prophesy what happens when:A. More sugar is external to the separation at 80 °C.B. The separation at 80 °C is zealous to 95 °C.C. The separation is cooled to capacity clime.2. Using the Kspdata adown, prophesy the products restraint the subjoined reaction:Ca2(aq) NO3-(aq) K(aq) F-(aq) -> ???Ksp Ca(NO3)2 = 1.6 x 10-3 Ksp CaF2 = 3.5 x 10-11Ksp KNO3 = 1.3 x 106 Ksp KF = 8.7 x 1053. You are granted with an aqueous separation containing 0.050 M Mg2 and 0.050 M Cu2 ions and are asked to aim to disunited them. What eagerness of OH- is needed to inaugurate subsidence of each cation? Ksp = 1.8 x 10-11 restraint Mg(OH)2; Ksp = 4.8 x 10-20 restraint Cu(OH)2. 4. Calculate how numerous mL of a 0.1 M NaOH separation was external to a titration adjustment of 100 mL of 0.1 M HCOOH (pKa = 3.75) separation to thrust a last pH of 5.1.5. 50 mL of 0.03 M HCl separation was external to 100 mL of 0.10 M acetic clever separation (CH3COOH, Ka = 1.8 x 10-5). What is the pH of the adjustment?6. Consider intermittently the preceding problem: What side of the acetic clever is dissociated antecedently and succeeding the observation of the HCl separation?7. Consider a separation of ammonia, NH3. An resembling toil of an ammonium chloride separation of the identical eagerness was external to the ammonia separation. How obtain this pretend the pH of the ammonia separation? Explain your confutation.8. You entertain 1.0 L of a restraintmic clever buffer that is 0.10 M in HCOOH and 0.050 M in HCOONa. The subjoined substances were external to this buffer in three disunited experiments: 1) 0.05 mol of HCl, 2) 0.05 mol of NaOH, 3) 0.05 mol of HCOONa. Which of the issueing separation(s) no longer capacity(s) as a buffer? Explain your confutation.9. What is the solubility of PbI2(s) in a separation saturated with another locally divisible iodide salt referable-absolute to PbI2(s) solubility in mere insinuate? Explain your confutation.10. Consider a separation of CaCl2 and Mg(NO3)2 in which the eagernesss of twain Mg2 and Ca2 are the identical, 0.01. M. Is it practicable to disunited Ca2 from Mg2 by exceptive subsidence of Mg(OH)2? To be ceremonious, is it practicable to precipitate 99.99% of magnesium outside precipitating any calcium as hydroxides? Restraint the end of artlessness, appropriate that the subsidence reactions do referable issue in any modify of the toil of the reaction adjustment. The Ksp values of the calcium and magnesium hydroxides are 6.5 x 10-5 and 7.1 x 10-12, respectively. Show your toil.
