 You're going to make a series of solutions from pH 1 to pH 13 by doing a serial dilution. In the second row of your 24 well plate, place 30 drops of distilled water. In well 1 of the first row, place 30 drops of 0.1 molar HCl. Take your water dropper and transfer three drops of the solution from well 1 to well 2. Now wrench your dropper several times with water and empty it into your waste beaker. Add 27 drops of water to the second well. You now have a total of 30 drops in your second well. This is a 1 to 10 dilution from the first well. Repeat this procedure by taking three drops from the second well and transferring it to the third well. Rinse out your dropper thoroughly with water. Add 27 drops of water. Take then three drops from that well and add it to the next well until you have all six wells. This should give you a pH of 1 through 6. Now take your basic dropper and add 30 drops of 0.1 molar sodium hydroxide to the last well in the third row. Transfer three drops of that solution to the next well. Rinse the pipette and then add 27 drops of water and mix. Repeat that procedure until you filled all the wells in that row. This should take you from pH of 13 down to pH of 8. When you've made all of your dilutions, add a drop of universal indicator to each of the wells. Swirl them. Share that your solution colors to the color chart provided.
