NaHC2O4--basic NH4Br--basic Na2CO3--basic KClO4--neutral Explain your choice. 9.94 c. 4.30 d. 3.00. b If 34.8-mL of 0.109 M NaOH were required to titrate the excess sulfuric acid, how many moles of sodium hydrogen carbonate were present in the original sample? ["ImageName"]=> Of course, pK_(a2) is the one that concerns us. The pH of a 0.100 M solution is 1.30. As mass / volume = molarity * molar mass, then mass / (volume * molar mass) = molarity. A: We have to calculate the pH of Solution. What is the pH of a buffer prepared by adding 0.607 mol of the weak acid HA to 0.609 mol of NaA in 2.00 L of solution? What is the pH of a buffer with 0.809 mol of weak acid HA to 0.609 mol of NaA in 2.0 L of solution? It will be most soluble in one of the last two. }); 2015-05-19 If 'a' g is the mass of NaHC2O4 required to neutralize 100 mL of 0.2M NaOH & 'b' g of NaHC2O4 required to reduce 100ml of 0.02M KMnO4 in acidic medium then, find relation between a and b. (Ka = 6.5 x 10-5 for benzoic acid), A buffer that is 0.271 M in acid, HA, and 0.150 M in the potassium salt of its conjugate base, KA, has a pH of 2.85. NA. Oxalic acid has a Ka of 5.4 x 10-2.
