Consider the following data on some weak acids and weak bases:acid baseKa name formula Kb name formula6.8x10-4 hydrofluoric acid HF 1.8x10-5 ammonia NH34.9x10-10 hydrocyanic acid HCN 1.7x10-9 pyridine C5H5NUse this data to rank the following solutions in order of increasing pH. In other words, select a '1' next to the solution that will have the lowest pH, a '2' next to the solution that will have the next lowest pH, and so on. solutiona) 0.1 M NaCN b) 0.1M NH4Brc) 0.1M KFd) 0.1M KBr

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.
