The standard reduction potential for the half-reaction HClO(aq) + H+(aq) + e- → ½Cl2(g) + H2O(l) is 1.61 V. What is the standard reduction potential for the following half-reaction? 2HClO(aq) + 2H+(aq) + 2e- → Cl2(g) + 2H2O(l) - Ans: 1.61 V Given that Eºcell = 0.60 V for a voltaic cell in which the following redox reaction takes place 2Rh(s) + 3Cl2(g) → 2Rh3+(aq) + 6Cl-(aq) and that the standard reduction potential for the half-reaction Cl2(g) + 2e- → 2Cl-(aq) is 1.36 V, calcul...

CHEM 163 Final Study (CHEM 163 WWU) Questions And Answers Predicting if a solid will form - ANS-Compare Qsp (not @ eq.) to Ksp (@ eq.) 1. Qsp>Ksp: rxn favors reactants, solid will form 2. Qsp<Ksp: rxn favors products, solid will not form --Don't forget, Q is a rxn quotient, exclude pure substances, coefficients become exponents Eq. Const. Expression - ANS--Coefficients become exponents -exclude pure substances (l), (s). These do not contribute to eq. Strength of weak acids - ANS-Ka...
