QUESTION 3 To answer Questions 3 through 7, consider a situation in which 25.00 mL of HCI (a strong acid) is titrated with NaOH (a strong base). Suppose that the initial pH of the acid solution, before any base is added, is measured to be 1.02. What is [H 30 *], the concentration of H 30 *, in mol/L, at the start of this titration? Type your numerical answer, without units, in the box provided. It is not necessary to use scientific notation, but if you choose to do so, be sure the use the format that Blackboard recognizes (7.55 x 10-3 would be typed as 7.55E-3 without any spaces). QUESTION 4 How many millimoles (mmol) of H 30 * are in the acid solution at the beginning of the titration, before any base is added? Type your numerical answer (no units!) in the box provided.
