Question

Many of the water properties lead to some crucial physical, chemical and biochemical processes that are closely related to environmental and health problems. Some people state:

(I) A relatively high dissolution of O2

in water is due largely to the dipolar property of water molecules.

(II) Although the density of water changes only slightly with temperature, its change can cause lake water turnover or stratification.

(III) Since water dissociation is so small (H2O ó H+ + OH-, Ka = 1.0 x 10-14), we can say that water does not participate significantly in any chemical reaction in aqueous systems.

(IV) Hydrogen bonding is an important chemical force involved in biological processes. This type of bonding is attributed to the strong interaction between OH- and H+ in water molecules.

Which of the above options are incorrect?

Question 2 options:

a)

(I), (IV)

(I), (II), (IV)

c)

(I), (III), (IV)
