1. General Chemistry II Jasperse Buffers/Titrations /Solubility. Extra Practice Problems General Types/Groups of problems: T Buffers General p1 Titration Graphs and Recognition p10. What Kind of Solution/pH at End? p2 Titration Calculations p11. Preparation and Recognition of Buffers p4 pH Estimations/Calculations after acid/base p12. are added (including at Equivalence Point). Buffer Calculations p5 Solubility Problems p14. Disrupted Buffers: After Acid or Base are Added p7 Impact on Solubility When Common Ions p16. are Present Titration-Related Problems p9 Impact of pH on Solubility p17. Key Equations Given for Test: For weak acids alone in water: For weak bases alone in water: [H+] = K a x[WA] [OH-] = K b x[WB]. pZ= -logZ pH + pOH = 14. General definition for p of anything [H ][HO-] = x 10-14. + KaKb= x 10-14 for conjugate acid/base pair For Buffer.
Dilution does not affect the pH because this concentration ratio doesn’t change upon dilution. 3. Research with biochemical systems commonly requires buffers because _____ a. that’s just the way it is. ... c. = 3.5 a solution of hypochlorous acid and sodium hypochlorite, K a ×10–8 d. = 5.8 a solution of boric acid and sodium borate, K a ...
