    Seven test tubes were prepared as follows:

    Tube 1: 5 mL of 0.1M HCl and 5 mL of water

    and tubes 2 - 7 were filled with 9 mL of water

    One mL of tube 1 was then poured into tube 2; 1 mL of tube 2 was poured into tube 3; 1 mL of tube 3 was poured into tube 4; 1 mL of tube 4 was poured into tube 5;1 mL of tube 5 was poured into tube 6 and 1 mL of tube 6 was poured into tube 7.

    Please help me calculate the concentrations of H3O+ and the pH of each acidic solution.
