Calculate [H3O+] and [OH–] for each solution at 25 °C. a. pH = 8.55
Calculate [H3O+] and [OH–] for each solution at 25 °C. b. pH = 11.23 c. pH = 2.87
Complete the table. (All solutions are at 25 °C.)
Like all equilibrium constants, the value of Kw depends on temperature. At body temperature (37 °C), Kw = 2.4×10–14. What are the [H3O+] and pH of pure water at body temperature?
The value of Kw increases with increasing temperature. Is the autoionization of water endothermic or exothermic?
Determine whether or not the mixing of each pair of solutions results in a buffer. e. 105.0 mL of 0.15 M CH3NH2; 95.0 mL of 0.10 M HCl
