Problem: A 15.0-mL sample of 0.100 M Ba(OH)2 is titrated with 0.125 MHCl.Calculate the pH for different points throughout the titration curve and make a sketch of the curve.

FREE Expert Solution

Plot the graph using the volumes at 0, 10, 30 and 50 mL HCl

a. 0 mL

[OH-] = 0.1 mol Ba(OH)2L  (2 mol OH-1 mol BaOH2)

[OH-] = 0.2 M

pOH = -log (0.2) = 0.699 

pH = 14-0.0699 = 13.3
