**Titration Example:****Experiment Details:**- 20 mL of 0.1M titrand is titrated with a 0.1M titrant.- Data points are collected at 1 mL increments.**Graph Explanation:**- The titration curve shows pH changes as the volume of titrant (in mL) is added, ranging from 0.0 to 50.0 mL on the x-axis.- The pH is plotted on the y-axis, ranging from 0.0 to 14.0.- The curve starts at a low pH, indicating an acidic solution, and sharply rises around the equivalence point, leveling off at a higher pH.**Questions:**(a) Is the species being titrated an acid or a base?(b) Is the species being titrated strong or weak?(c) What is the value of $ K_a $ (if a weak acid) or $ K_b $ (if a weak base) for the species being titrated? If the species is strong (100% dissociated), enter 999.

From the pH vs volume of titrant plot we can figure out whether titrant and titrand are acid or…

Please do the values of 160mL to 260mL, I have already done 0-130mL. I am also having trouble creating the titration chart. Thank you!
Weak Base + Strong Acid Titration - Example Problem: Titration of 25 mL of .1 M NH3 With .1 M HCl: a. 0 mL. b. 12.5 mL. c. 20 mL. d. 25 mL. e. 30 mL.
For each of the three titrations, determine the expected pH at each of the following 4 points in the titration. Assume that all acids are exactly 0.1 M and that all bases are exactly 0.2 M for purposes of your calculations. Round your final pH values to the nearest 0.1 pH units since that is how we read the experimental values. The 4 points for which the pH values are to be calculated are: a) after 0 ml of base have been added (initial pH) b) after 10.0 mL of base have been added (halfway to the equivalence point) after 20.0 mL of base have been added (equivalence point) c) after 20.0 mL of base have been added (equivalence point) d)after 25.0 mL of base have been added (5 ml past the equivalence point)
The end point for a titration can be determined graphically. The end point volume for a first derivative plot corresponds to: A. the volume base added where the first derivative curve crosses the x-axis. B. the volume base added where the first derivative curve has minimum slope. C. the volume base added where the first derivative curve has a maximum negative slope. D. the volume base added where the first derivative curve crosses the y-axis. E. the volume base added where the first derivative curve has maximum slope.
