Question

When the stopper is removed from a partly filled bottle containing solid and liquid acetic acid at 16.7 °c, a strong vinegar like odor is noticeable immediately. is the system enclosed in the bottle homogeneous or heterogeneous? explain?

Answer 1

Base from the problem description, there would be three phases that would be present in the bottle. The solid phase and the liquid phase are observed in the bottle while the gas phase is being detected from the odor that we noticed. Acetic acid is also known as ethanoic acid. It is a colorless liquid compound at STP. It has a noticeable sour smell. It is classified as a caboxylic acid due to the presence of -COOH group. The triple point of this substance is found at a temperature of 16.7 degrees Celsius. At this temperature, all of the three phases of matter exist with each other which can be observed in the problem.

Answer 2

Step-by-step explanation:

A solution whose constituent particles differ in proportion or when particles are easily separated out then this type of solution is known as heterogeneous solution.

For example, sand in water can be easily separated out as their particles differ in size.

Thus, we can conclude when solid is placed in acetic acid at 16.7 °c, a strong vinegar like odor is noticeable immediately. This system enclosed in the bottle is heterogeneous.
