a.) Write a balance equation for the dissociation of acetic acid ( HCH3CO2) in water, include state symbols, charges and label every reactant and product as Acid or Base.

b.) If acetic acid has a Ka = 1.8 x 10-5 exponent, what is the pH of a buffer solution that contains 0.100 M acetic acid and 0.120 M sodium acetic.

c.) Write the equation for the reactuon if HNO3 is added to this buffer, include all state symbols.

d.) When 0.020 mol HNO3 is added to 1.0 L of the buffer system described in part b and pH changes slighlty. does the pH increase or decrease? why explain.
