Calculate the concentrations of H3O+ and the pH of each acidic solution. Since HCl is a monoprotic acid (an acid that donates only one proton or hydrogen atom permolecule to an aqueous solution), the H3O+ concentration is equivalent to the HCl molarity. Experiment 1: pH Indicators for Acids 1. From the Containers shelf, take seven clean test tubes and put them on the workbench. 2. Label one test tube "#1." From the Materials shelf, add 5 mL of 0.1 M hydrochloric acid (HCl) and 5 mL of water to #1. (Double-click on a test tube to label it.) 3. Label each of the remaining test tubes, #2 - #7. Add 9 mL of water to the each of them. 4. You will now create a series of successively diluted acidic solutions as follows: (a) Pour 1 mL from #1 into #2. (b) Pour 1 mL from #2 into #3. (c) Pour 1 mL from #3 into #4. (d) Pour 1 mL from #4 into #5. (e) Pour 1 mL from #5 into #6. (f) Pour 1 mL from #6 into #7. 5. Add two drops of bromothymol blue to each test tube and observe the color of the solutions. Record your results. 6. Repeat steps 1 - 4; add two drops of methyl yellow to each test tube and observe the color of the solutions. Record your results. 7. Repeat steps 1 - 4; add two drops of bromocresol green to each test tube and observe the color of the solutions. Record your results. 8. Repeat steps 1 - 4; add two drops of red cabbage extract to each test tube and observe the color of the solutions. Record your results.
