When determining the amount of an oxidant present by titration, you can use iodine and starch as an indicator. 1. First, the oxidant, like hypochlorite, oxidizes.
a. neutral iodine into iodide ion.
b. iodide ion into neutral iodine.
c. iodate polyatomic ion into iodide ion.
2. When starch and iodine are both present, the solution is.
a. blue-black.
b. brownish yellow.
c. clear.
3. During the titration, the titrant, like thiosulfate, reduces the.
a. iodide ion into iodate polyatomic ion.
b. neutral iodine into iodide ion.
c. iodide ion into neutral iodine.
4. When the iodine has completely reacted at the endpoint of the titration, the solution should become.
a. clear.
b. blue-black.
c. brownish yellow.

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 to this question is 3.
