pH is the concentration of acid/alkali when dissolved in water. That's why pH7 is water. Some salts have hydrogen ions (what makes an acid an acid) but not all, so some salts are acidic.

Acids have one of the hydrogens from a water molecule, bases have the other hydrogen and the oxygen from a water molecule. when an acid and a base meet they react and the hydrogen and oxygen bonds together to make water. This is why water manipulation can lead to acid manipulation.
