What does it mean when a substance has a pH greater than 7?
#K_w = ["H"^(+)]["OH"^(-)] = 10^(-14)#
#"pH" = -log["H"^(+)]#
How would you describe a solution with
It is alkali
A substance with a pH less than 7 is acidic, greater than 7 is alkali and equal to 7 is neutral.
As mentioned by Truong-Son N, this is assuming that the substance is at room temperature (
pH actually refers to the concentration of
Hope this helped; let me know if I can do anything else:)
