If the pH at the equivalence point for titration of a monoprotic weak acid with NaOH is 9.00, and 10 mL of base is required to reach the equivalence point, how would you determine the pKa of the acid? the pKa is 9.00 determine the pH after 5 mL of base is added; this is the pKa determine the pH when 20 mL of base is added; this is the pKa the pKa is -log(9)
In a titration, 25 mL of 0.10 M weak diprotic acid solution was titrated by 0.10 M sodium hydroxide, NaOH, and produced a titration curve listed below.

10.3 Titration curves are shown for two diprotic bases titrated with hydrochloric acid. Both bases are in the table of Ko values that is provided. Identify which base is titrated in each titration curve. Briefly explain how you know which base it is. (Hints: What is the relationship between Ko and PK, for a diprotic base? What is the relationship between pK, and pH in titration curves for weak acids and bases?) (a) Which weak base from the table is...
24A) 40mL of 0.2 M formic acid is titrated with a strong base (NaOH= 0.5 M). Determine the pH before any base has been added. Please show steps and please explain why the answer is what it is. 24B) The 40mL 0.2 M formic acid is titrated with a 6.0mL of strong base. Here NaOH can be treated as a conjugate base and formic acid is the acid. please show steps and explain! Us (24-25, Acid/base, aqueous equilibrium) 24A) (4...
An unknown acid is titrated with a strong base (NaOH) to produce the above titration curve. Key points on this graph reveal important information about the substance and the solution created with it. What volume of NaOH is needed to reach the equivalence point (the point where you added equal moles of NaOH to the acid)? Select one of the following : ["10 mL", "5 mL", "20 mL", "30 mL", "40 mL", "25 mL", "15 mL", "35 mL"] ...
