3. (13 pts.) Mercaptoethanol (HSCHCH3OH) dissociates in water as shown in the below balanced equation. All questions below relate to this equation. HSCH2CH2OH (aq) = H(aq) + SCH2CH2OH(aq) Once this reaction reaches equilibrium, its equilibrium constant K is 1.91 x 10-10 at 25°C. a.) (1 pts.) Write the equilibrium expression for the above reaction at 25°C. b.) (3 pts.) The equilibrium mixture, at 25 °C, consists of 0.5 MH and 0.025 M HSCH2CH2OH. Calculate the equilibrium concentration of SCH,CH2OH and include proper units, if any. c.) (3 pts.) The equilibrium constant for the above reaction is 1.91 x 10-10 at 25°C. Explain what this information this tells us about this reaction. d.) (4 pts.) In the above reaction, the reactant mercaptoethanol is behaving as what type of substance? Are there any other reactants participating in addition to the mercaptoethanol? Explain thoroughly. e.) (2 pts.) Is mercaptoethanol an electrolyte? If so, is it an "effective" electrolyte? Explain thoroughly.
