Question | Answer |
What is the relation of K(sp), solubility constant to soulubility? | K(sp) is directly related to solubility; therefore the larger the K(sp) the more soluble the product |
What is the common ion effect? | Another form of Le Chatelier's Principle, the the decrease in the solubility of a salt occurs because another salt is added that contains one of its ions. |
What is the relatonship bw autoionization of water K(w) and temp | it increases when temp increases |
polyprotic | can accept or donate more than one H+ |
high [H] means... | low pH and the solution is acidic |
pH + pOH = | 14 |
pH = | -log[H] or -log[H3O+] |
pOH = | -log[OH] |
What is the relation bw K(a) and pKa? | The larger the K(a) value the smaller the pKa value and therefore the stronger the acid |
What is the Henderson-Hasselbalch equation? | pH = pKa + log {[conjugate base]/[weak acid]} |
what happens at a half-equivalence point? | the pKa equals the pH |
K(w) | = [H3O+][OH-] |
Titration equation | pH = [vol acid]/ [vol base] |
pKa + pKb = | 14 |
