Calculate the pH of each and determine whether each of the following solutions is acidec or basic.
a) [H^+]=1.0 e-11M solution
b) [OH^-]=1.5 e-3M solution
c) [H^+]=5.2 e -5M solution

  • chem -

    pH= -log [H+] pH < 7 is acidic and pH > 7 is basic.

    for example

    pH= - log [1.0e-11M]
    pH= 11
    therefore basic solution.
