Imagine that you are in chemistry lab and need to make 1.00 LL of a solution with a pHpH of 2.60.

You have in front of you

  • 100 mLmL of 6.00×10−2mol L−16.00×10−2mol L−1 HClHCl,
  • 100 mLmL of 5.00×10−2mol L−15.00×10−2mol L−1 NaOHNaOH, and
  • plenty of distilled water.

You start to add HClHCl to a beaker of water when someone asks you a question. When you return to your dilution, you accidentally grab the wrong cylinder and add some NaOHNaOH. Once you realize your error, you assess the situation. You have 83.0 mLmL of HClHCl and 90.0 mLmL of NaOHNaOH left in their original containers.

Assuming the final solution will be diluted to 1.00 LL , how much more HClHCl should you add to achieve the desired pH?

ORGANIC CHEMISTRY (TLC lab) if you used a solution of 90% ethyl acetate / 10% hexane instead of 10% ethyl acetate / 90% hexane to elute your TLC plates, what would you expect to see? Would the Rf valaues increase of decrease for each compound? Explain in detail. Rf values Naphthalene = 0.44 9-fluorene 0.56 Benzophenone = 0.39 Fluorene = 0.88 4-nitroaniline = 0.28 4- methoxyacetophenone = 0.24
