Percent ionization - Study guides, Class notes & Summaries

Predicting if a solid will form correct answer: 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 correct answer: -Coefficients become exponents -exclude pure substances (l), (s). These do not contribute to eq. Strength of weak acids correct answer: Ka= "big" number, "...

there is a decrease in products - if K <<<< 1 of a weak acid, then (concerning products) decrease in pH - an increase in K and products will result in (concerning pH) Ka - equilibrium constant for ionization of acid increases - if the percent ionization increases, what happens to acid strength? K decreases - what happens to K as you deprotonate acids? weaker - do acid become weaker or stronger as you deprotonate them? no - do SA/SB have conjugates?
