What is the pH of 0.038 M HCl? What is the hydronium ion concentration in a solution with pH = 2.26? An unknown bottle of acid says 0.000010 M on the label. The measured pH is 7.66. This implies that the unknown acid has which of the following? Which of the acids below will have the lowest pH in a 0.000010 M solution of the acid? (Hint: Larger Ka values favor products and smaller Ka values favor reactants.) Write net Brønsted equations that show the acidic or basic nature of the following solutions in water. For polyprotic species (vitamin C, lemon juice, and washing soda), show only one proton transfer. Remember that spectator ions are not included. (Use the lowest possible coefficients. Omit states-ofmatter in your answer.) (a) vinegar (acetic acid, HC2H3O2) b. bleach (sodium hypochlorite, NaOCl) (c) ammonia (NH3)
