Answer 1

Answer #1

pH = -log [H+]

at concentration = 1 x 10-8 M,

pH = -log [1 x 10-8] = 8

at concentration = 1 x 10-9 M

pH = -log [1 x 10-9] = 9

Therefore, the pH will be

b. Higher than 7

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...
