Calculate the molar solubility of ag2co3:
a) in water;

b) in a solution of 0.100 mol/l na2co3;

c) in a buffer solution with ph = 9.00.

(pkps (ag2co3) = 11.09; pka1 (co2) = 6.35; pka2 (co2) = 10.33)

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

its b it was a compound
