Hi,
I need help with this question, thank you!
A 10.00mL sample of 0.1000M an acid (pKg) = 2.89; PK 2 = 5.51) was titated with 0.1526M NaOH. Sketch the graph of pH versus Vook for the titration of this acid through the addition of 25.00mL of NaOH. (3 points) Indicate the numerical pH values for the initial (i.e. before addition of NaOH), half-equivalence, and equivalence points; as well as the pH once the full 25.00ml NaOH has been added....

Hi! I need help on this lab report question and I can't seem to figure it out! Essentially, in this experiment, we titrated 0.095189 M NaOH into a 0.5 M phosphoric acid solution. The volume of NaOH at the first equivalence point is 3.66 and the corresponding pH is 3.61. What is the concentration of the phosphoric acid based on the 1st Equivalence Point? (M) We're given the volume of Na
