  1. The definition of pH is:
    pH=-log[H3O+]
    An equivalent statement is:
    [H3O+] = 10^-pH
    The hydronium concentration is the antilog of the (-pH)
    For this example,
    [H3O+] = 10^-10.5 = ??
    The definition acid, basic, and neutral pH's should be something you can look up in your textbook or other assigned materials.
