Answer the following by selecting all correct answers.
(a) Dynamic equilibrium
O is a condition where two opposing processes are occurring at the same rate.
O can only occur in water.
O is used to describe what happens when weak acids or weak bases are added to water.
O is used to describe what happens when strong acids or strong bases are added to water.
(b) What will happen if acetic acid (HC2H3O2) is added to water?
(7) Calculate the pH of each of the following solutions:
(a) 0.1000M Propanoic acid( HC H O,,K=1.3x105)
(b) 0.1000M sodium propanoate (Na C HỎ)
(c) 0.1000M HC₂H₂O, and 0.1000M Nа С¸¸0₂

(d) After 0.020 mol of HCl is added to 1.00 L solution of (a) and (b) above.
(e) After 0.020 mol of NaOH is added to 1.00 L solution of (a) and (b) above.
Nitrogen is discharged from wastewater treatment facilities into rivers and streams, usually as NH₃ and NH₄⁺: NH₃(aq)+H₂O(l) → NH₄⁺(aq)+OH⁻(aq) K(b)=1.76X10⁻⁵ One strategy for removing it is to raise the pH and “strip” the NH₃ from solution by bubbling air through the water. (a) AtpH 7.00, what fraction of the total nitrogen in solution is NH3,defined as [NH₃]/([NH₃] [NH₄⁺])? (b) What is the fraction at pH 10.00? (c) Explain the basis of ammonia stripping.
