In the simulation, open the Custom mode. The beaker will be filled to the 0.50 L mark with a neutral solution. Set the pH to 4.75 by using the green arrows adjacent to the pH value indicated on the probe in the solution. Once you adjust the pH, note the corresponding OH ion concentration in M as given in the graphic on the left side of the simulation. Make sure to select the option "Concentration (mol/L) above the graphic. Select on the Logarithmic scale below the graphic. Find the pOH of the solution. Express your answer numerically to two decimal places.

Learning Task 11: Try to solve the following titration problems. Show your complete solution. 1. An acid-base titration is performed in which 26.05 mL of 0.1000M H₂SO4 solution was needed to reach the endpoint of a 25mL NaOH solution with unknown concentration. The chemical reaction involved in this titration is as follows: H₂SO4 (aq) + 2NaOH(aq) → H₂O (1) + Na2SO4 (aq) Calculate for the molarity of the NaOH solution. 2. Suppose a titration needed 27.15 mL of 0.2497M HCl solution to completely react 25.00mL of Ba(OH)2 solution of unknown concentration. Identify and balance the chemical equation involved, then calculate for the concentration of the Ba(OH)2 solution.
