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.

Prepare another 5 cuvettes with different concentration of Pi using the stock 1mM Pi, 0.5mM PNPP solution (in water) and 0.2M Tris-HCl, pH=8.00. For this part, the concentration of PNPP will remain constant at 0.150mM. Fill the table below (before coming to lab) and use it to prepare your cuvettes. The completed table must be in your pre-lab. Your blank for each reaction is the PNPP mixed with Tris-HCL and Pi. Again, prepare one cuvette at the time to minimize exposure of the PNPP to the air. You can prepare your next cuvette while your previous one is being read. previous one is being read.

Q4. In this experiment, we add hydrochloric acid to our unknown sodium hydroxide solution during the titration. Sketch a sample pH curve showing how the pH of the titrated solution changes as we add more titrant. Be sure to label both axes of your graph and indicate the position of the equivalence point. C10 p Con Q5 You initially begin with a 0.1593 M hydrochloric acid solution. If you had a 125.0 mL sample of this hydrochloric acid solution, how many grams of HCl would be present in the sample? Show all work. Yourde tobl Q6 Write out a stepwise procedure (list of numbered steps) that you plan to execute when you come to lab to do the titration.
