Phenoxide ion (C₆H₅O⁻) is a weak base with kb = 7.70 x 10⁻⁵ what is the pKa of the phenol C₆H₅OH(conjugate of phenoxide ion) calculate the pH of a 0.50 M aqueous solution of [C₆H₅O] Do you think the pH of 1.0 M tri-methyl ammonium(CH₃)_3NH⁺) pKa = 9.80 will be higher or lower than that of 10 M C₆H₅CH?
What is the difference in pH values for the two acids?
Hydrosulfuric acid also known as hydrogen sulfide is a diprotic acid Its two stages of are shown below: H₂S(aq) = H⁺ + H₅(aq) Kal= 5.70 x 10⁻⁸H₂S(aq) = H⁺ + H₅(aq) Kal = 100 X 10⁻⁹.
