Can you please do number 14 III.  Can you tell us how to get the volume.  I want to know how to calculate the volume in this titration of ch3nh2. See pic.. This is not a graded question as it is a practice question . I am 60 years old and helping my son prepare for the AP exam in a few months. We do questions at the back of the textbook by Zumdahl and Zumdahl

Consider the titration of 80.0 mL of 0.100 M Ba (OH), by 0.400 M HCI. Calculate the pH of the resulting solution after the following volumes of HCI have been added. a. 0.0 mL pH = b. 20.0 mL pH = c. 30.0 mL pH= d. 40.0 mL PH= e. 90.0 mL pH = Submit Answer Try Another Version 1 item attempt remaining

30. Indicate the FALSE statement about pH indicators and their use in titrations: A) A pH indicator suitable for titrations of strong bases with strong acids cannot be used for titrations of strong acids with strong bases. B) pH indicators should be used sparingly (in small amounts) as they are weak acids/ bases, and thus could affect the volume of titrant used. C) An indicator should be selected such that its pKits value matches the equivalence point pH. D) pH indicators all contain at least one acidic group that can be deprotonated to form a differently colored conjugate base. E) The colours of the acid and base forms of a given pH indicator depend on their chemical structures.

Hd 14 12 10 8 6420 80 120 160 40 Volume of base added (mL) The figure shows pH as a function of volume of base added. The pH is measured from 0 to 14 on the y-axis, while the volume of base added is measured from 0 to 160 milliliters on the x-axis. The curve of the plot goes up gradually from pH 2.3 at 0 milliliters to pH 5.8 at 49 milliliters, next the plot goes up steeply to pH 11.8 at 51 milliliters, and finally the plot goes up gradually to pH 12.2 at 160 milliliters. ✓ Correct An equilibrium problem based on the initial concentration and Ka of a weak acid should be solved for aqueous solution of the weak acid. This is true for the initial state of titration, when no base has been addition of a small amount of a strong base turns this solution into a buffer whose pH is calculated in way. Part D At what volume of added base does pH =…

True or False To calculate the pH before the start of the titration of a weak acid with a strong base requires an I.C.E table.   True or False You can use the Henderson-Hasselbalch equation to calculate the pH at the equivalence point of a weak acid/strong base titration.
