The pKa of acetic acid, HC2H3O2 is 4.58. A buffer solution was made using an unspecified amount of acetic acid and 0.4 moles of NaC2H3O2 in enough water to make 1.87 liters of solution. It's pH was measured as 3.11. How many moles of HC2H3O2 were used? Report answer with 2 places past the decimal point.

Experiment : You took 0.51 g of an unknown weak organic acid and dissolved it in 50. ml of water. Then titrated the solution with 0.100 M NAOH and measured the pH after adding 5.00 ml increments of the base, and collected the following data. NaOH (ml) PH 0.0 2.45 5.0 2.95 10.0 3.92 15.0 4.05 20.0 4.35 25.0 8.10 35.0 12.01 40.0 12.20 45.0 12.50 50.0 12.8

pka=pH halfway to the equivalence point. what is the equivalence point volume? it says to do so by locating the inflection point of the curve. but i'm not sure what the inflection point of the curve is. it says: using a ruler, draw a vertical line that crosses the inflection point and extend this line so it crosses the horizontal axis (use vertical minor gridlines to guide vertical ruler) to find volume base at the equivalence point.

Lola and Richie were tasked to analyze the acidity of a 10.0-mL fermented milk sample diluted with water in a 250-mL volumetric flask. Mola obtained a 15.0-mL aliquot of this solution, diluted it to 50.0 mL, and then titrated this diluted sample. Titration data were given to Rity and she found out that the 50.0-mL sample contains 0.21 mmol of lactic acid. MW: Lactic Acid (90.08)1.What is the lactic acid concentration (in M) of the titrated sample?2. Determine the lactic acid content (in M) of the 10.0-mL fermented milk sample.3. What is the lactic acid concentration (in %w/v) of the 10.0-mL fermented milk sample?
