Assignment:
Find the pH of a solution prepared by dissolving all of the following compounds in one beaker and diluting to a volume of 1.00 L: 0.180 moles acetic acid (pKa=4.75), 0.180 mole sodium acetate, 0.060 mol H2SO4, and 0.060 mol NaOH. Assume sulfuric acid dissociates completely (i.e. it is a strong acid).
Consider the titration of 25.00 mL of a solution that contains 0.0450 M I- by a 0.150 M solution of Cu+ to form the precipitate CuI. What are the concentrations of Cu+ and I- after 10.00 mL of titrant have been added? CuI Ksp = 1.0x10-12
As the pKa of weak acid get large (increases) the strenght of thier conjugate bases become:
a)stronger
b)weaker
c)stays the same
d)can't be compared
Provide complete and step by step solution for the question and show calculations and use formulas.
