EXAMPLE 19. STRONGSAGDE BASE EQUILIBRIUM CALCULATION EMBRE What is the pH of a river immediately after a train wreck releases 400 liters of concentrated (14 M) hydrochloric acid over a period of 1 hour? The river flow rate (Q) is 100 m/s, and assume that the stream is pristine and dilute (i.e., no other acids or bases are present). The pK, for HCl is 3. Engineering Department at Gutech University 15
