Problem 7-28
Look up the equilibrium constant for the ion-pairing reaction in Appendix J. (a) Use the systematic treatment of equilibrium to find [Zn2] in 0.010 F ZnSO4. Neglect activity coefficients and any other reactions. (b) Use the answer from part (a) to compute the ionic strength and activity coefficients of Zn2 and . Then repeat the calculation using activity coefficients. Repeat the procedure two more times to find a good estimate of [Zn2]. What percentage is ion paired? What is the ionic strength of the solution? (c) Two possibly important reactions that we did not consider are acid hydrolysis of Zn2 and base hydrolysis of . Write these two reactions and find their equilibrium constants in Appendixes I and G. 7-2

CH 1010: General Chemistry Dr. Ava Kreider-Mueller Chapter 6: Intermolecular Forces Attractions Between Particles Terms Topics [Key Terms] Gases - particles are independent of one another, feel little attractive force, and are free to move about randomly. Liquids- particles are strongly held together by attractive forces which are strong enough to hold the particles in close contact while letting them slide over one another. Solids- the particles are held by attractive forces which hold the particles in place. Intermolecular forces- act between molecules to hold them together at certain temperatures Van d
