Which statement below is true about the relative lifetime of a hydrogen bond, compared to the rate of water’s ionization to hydroxide ions and hydronium ions?

#SCPH05 I Biotechnology
  1. The strength of hydrogen bonding makes its dissociation much slower than the ionization of water.

  2. The rate of dissociation of a hydrogen bond is the same order of magnitude as the rate of ionization of water.

  3. The two rates are linked in such a way that the more the water is ionized, the stronger and longer lasting hydrogen bonding will be.

  4. The lifetime of a water molecule before it is ionized is about 109 greater than the lifetime of a hydrogen bond.
