Use Table B in your Student Guide to answer the questions about ion concentrations. A solution with a pH = 13 has approximately how many moles of OH– ions per liter? How many moles of H+ would this same solution have per liter? (Use the decimal form of your answer.) A different solution with an H+ concentration of 1.0 × 10–4 would have a pH = .

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.

the answer is d.) potassium
