For an aqueous acidic solution, which of the following is true? o [H3O+] < [OH-] O [H3O+] = [OH-] O [H3O+] > [OH-] O 2 x [H3O+] = [OH-]
Typically the concentration of hydronium, H3O+, or hydroxide, OH−, ions in an aqueous solution is less than 1 M. It is not uncommon to have hydronium ion concentrations that are much smaller, such as 2.60×10−5. pH, therefore, is a convenient way to restate the hydronium concentration. pH is equal to the negative log of a hydronium ion concentration in solution: pH=−log[H3O+] Access the pH calculation simulation, which will open in a new window. Edit the concentration by typing a value...
