Which of the following statements about acid and base variables is false? log base 10 is used to to go in and out of the p function the Kb expression associated with a base reacting in water will have hydronium [H3O*] as a product in it there are 7 strong acids and all acids, all other acids are considered weak in comparison Op function (which equals negative log of the variable in question) is a way to scale numbers into a smaller range A strong acid completely dissociates into its products and therefore has a high Ka value

If a 0.15 M aqueous solution of the weak acid HF has a pH of 5.12, what is the Ka? The reaction is provided below: HF + H₂0 F¯ + H₂O+ O 3.0 × 10-5 48 O 1.8 × 10-5 1.3 x 10-10 3.9 × 10-10
