Question

1. Which of the following is the best description of a refluxing solution? Circle one.
   1. A refluxing solution is one which reacts upon heating.
   2. A refluxing solution in one in which toxic by-products are released as gases.
   3. A refluxing solution is one in which a solution is vaporized and condensed into the same vessel.

2. Boiling chips and stones, and applicator sticks are added to liquids before heating.Circle one.

1. to make the liquid boil faster.
2. to prevent superheating.
3. to cool the boiling liquid.
4. to ensure even boiling or to reduce bumping.

Answer 1

Answer – We know refluxing process means the technique in which formed vapor gets condensed and again mixed into the original sample.

The refluxing solution means first, solution heated and turn into the vapor. Then this vapor condensed and formed again solution and revert back into the original solution. So the refluxing solution is best described with option number c. A refluxing solution is one in which a solution is vaporized and condensed into the same vessel.

The boiling chips are insoluble and porous silicon carbide or calcium carbonate stones. Boiling chips and stones, and applicator sticks are added to liquid before heat is to ensure the boiling and prevent the bumping by avoiding loss of solution.

So, option d is best to describe the boiling chips and stones, and applicator sticks are added to liquid.
