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= "big" number, "stronger" weak acidKa= "small" number, "weaker" acid --->can rank weak acids based on their Ka Arrhenius Acids and Bases - ANS-Acid: Cmpd. that donates an H+ in H2O Base: Cmpd. that donates an OH- in H2O Percent ionization - ANS-deg. of ionization*100 --more useful to us --this is the percent of the molecule that broke apart --almost always <10% Voltaic cell notation - ANS...
