Phenol, once known as carbolic acid, HC6H5O is a weak acid. It was one of the first antiseptics used by Lister. Its Ka is 1.1 x 10-10. A solution of Phenol is prepared by dissolving 14.5g of phenol in enough water to make 892 mL of solution. For this solution, calculate the pH. Hint: Determine the initial concentration using the formula of molarity.
Each value represents a different aqueous solution at 25 °C. Classify each solution as acidic, basic, or neutral. [H+] Acidic = 6.8 × 10-11 [H+] = 1.0 x 10-7 pOH = 1.15 он- pOH = 13.54 pH = 5.65 Basic Answer Bank = 1.2 x 10-5 [OH-] = 3.4 x 10-13 pOH = 7.00 [H+] = 4.1 x 10-3 pH = 9.84 Neutral
Calculate the pH of the solution. Assume 1.0 L of solution. You must identify the type of solution before calculating the pH. Express all pH values to two decimal places. 0.180 moles NaOH and 0.400 moles HC2H3O2 Ka (HC2H3O2) = 1.8 x 10-5
