d. As the pH approaches 0, what happens to the concentration of OH ions? 2. Use the following below to complete the table. Then use the completed table to answer the questions below. a. Open the pH Scale Phet simulation you used in the lab and navigate to the "Micro" tab at the bottom of the screen. b. Choose a substance. The original volume added to the beaker is 0.5 L. At that volume, use the pH probe to measure the those values in the table. c. Next add water to get the solution to 1 L and re-measure the pH, [H3O+], and [OH-]. Record those values in the table. d. Reset the lab and repeat these steps for 3 more substances so that you end up with some acidic substances and some b Trial 1 Trial 2 Trial 3 Trial 4 Substance Choose... Blood Choose...
