21. Problem How much greater is the [ H + ] in a solution with pH 2 than in a solution with pH 6? Answer: pH of 2 = [ H + ] of 1.0 x 10 -2 = 1/100 M pH of 6 = [ H + ] of 1.0 x 10 -6 = 1/1,000,000 M 10,000 times greater

Notes de l'éditeur
2 corners are orbitals with unshared electrons and a weak negative charge 2 are occupied by hydrogen atoms that have polar covalent bonds
Only a hydrogen ion is actually transferred The transferred proton binds to an unshared orbital of the second water molecule. The water molecule that loses the proton
There is only 1 molecule out of 554,000,000 water molecules that is dissociated.
