Acid and Base Titration Curves

Q. Hi there, thank you so much for your help. The information missing is a titration graph with the equivalence point between about 7.8 pH and 25ml of NaOH A 50.0 mL sample of a solution of a monoprotic acid is titrated with a 0.115 M NaOH solution. The titration curve above was obtained. The concentration of the monoprotic acid is about ________ mol/L. Answers: 25.0 0.100 0.120 0.0600 0.240 I did the calculations and I got 0.0611 mol/L, but I am still a little confused about it. Could you help me!!

Acid and Base Titration Curves

Q. Stuck on this one!! Sketch a titration curve for the titration of 30.00 mL of 0.050 M HNO3 (aq) with the addition of 0.050 M LiOH (aq). Is the pH at the equivalence point(E.Q.P) equal to 7, greater than 7, or less than 7? How many mL of LiOH (aq) are added to reach the E.Q.P? How many mL of LiOH (aq) are added to reach the point half way to the E.Q.P?
