Document Summary
Water chemistry: polar molecule, good solvent, ph 7. Ph = -log[h+: in any solution of water, some water molecules exist as protons (h+) and hydroxyl ions (oh-, the ph measures the concentration oh h+ on an inverse scale. Low ph indicates a high concentration of protons [h+]>[oh-] (acidic) High ph indicates a low concentration of protons [h+]
