Question

A student set up a test tube containing sodium bicarbonate and topped it with a volumeter, but forgot to add the Elodea plant! Which of the statements below gives the result that the student would be likely to observe?
A. The level of liquid in the volumeter would rise due to diffusion.
B. The level of liquid in the volumeter would remain constant since gas is being produced and used at the same rate.
C. The level of the liquid in the volumeter would remain constant since gas is neither being produced nor being used.
D. The level of liquid in the volumeter would fall since there is less mass in the test tube.
E. The level of liquid in the volumeter would fall since atmospheric pressure is greater than the pressure within the test tube.

Answer 1

C. The level of the liquid in the volumeter would remain constant since gas is neither being produced nor being used.

Volumeter can be described as any instrument that is employed for measuring the volume of a solid, liquid, or gas.

Sodium bicarbonate when dissolved in water forms carbonic acid and sodium hydroxide. This carbonic acid breaks down further to form water and carbon dioxide gas.

The carbon dioxide produced can be used by the Elodea plant for photosynthesis which is a process in which carbon dioxide is used up to create oxygen and energy.

However, as the Elodea plant was not added in this case therefore sodium bicarbonate was neither used up nor it was being produced therefore the level of the liquid in the volumeter would remain constant.
