Interpretation:
Correct statement about methods for separating mixtures.
Concept introduction:
Filtration is a process of passing gas or liquid through the filter. The fluid that passes through the filter is termed as filtrate and the other remainingpart is termed as residue.
Answer to Problem 17STP
Correct Answer: Option (b), filtration depends on the differences in the size of particles.
Explanation of Solution
Reason for correct option: The filter is an important technique to separate the mixtures. The process of filtration depends on the mixture’s physical characteristics. Some parameters are size distribution of droplets or particles, shape of the particles, etc. Hence, this is the correct option.
Reasons for incorrect options:
Option (a), Distillation results in the formation of solid particles of a dissolved substance. The distillation process is used for separating the mixture of two different liquids. This process is not used to separate different solid particles. Hence, this is an incorrect option.
Option (c), Separation depends on the chemical properties of the substance involved. Separations exploit modifications in physical or chemical properties (such as shape, size, density, chemical affinity, or mass) between the constituents of a mixture. Hence, this is an incorrect option.
Option (d), Chromatography depends on the different boiling points of substances. The chromatography process is used for the separation of a component from its multicomponent mixture. The component dissolves in liquid can be separated from the mixture. There is no relation to the boiling point of the component. Hence, this is an incorrect option.
Option (e), Sublimation can be used to separate two gases present in the mixture. Sublimation is a processin which, the solid-state is transferred to the gaseousstate without transforming ina liquid state. This process is also termed as conversion between solid to gas. Hence, this is an incorrect option.

- Please do not use AI. AI cannot "see" the molecules properly, and it therefore gives the wrong answer while giving incorrect descriptions of the visual images we're looking at. All of these compounds would be produced (I think). In my book, I don't see any rules about yield in this case, like explaining that one product would be present in less yield for this reason or that reason. Please explain why some of these produce less yield than others.arrow_forwardPlease answer the question and provide detailed explanations.arrow_forwardAll of these compounds would be produced (I think).
