Question

Name:
(a) two substance which can sublime
(b) two substances soluble in water
(c) two substance insoluble in water
(d) four substances that can be used as filters

Answer 1

Hint :In the above-mentioned question, we will learn about sublimation, solubility, and insolubility, as well as the substances that are employed as filters. We'll also learn about their respective examples and a little more about them.

Complete Step By Step Answer:
(a) Two substance which can sublime
Sublimation is the process by which a solid transforms into a gas without first becoming a liquid. Sublimates are chemicals that are undergoing sublimation.
$Solid\mathop \Leftrightarrow \limits^{Heating} Gas$
Ammonium Chloride is white solid on heating it sublimes and Naphthalene balls are the two examples of substance that sublimes.
(b) Two substances soluble in water
Sugar and salt are both solvents, as is water. When sugar or salt is introduced to water, the positive ions (anions) attract the sugar or salt's negative ions, while the negative ions (cations) attract the sugar or salt's positive ions.As a result, solubility refers to the ability of sugar or salt molecules to combine with water molecules.
Sugar and salt are the examples which are soluble in water.
(c) two substance insoluble in water
The term "insoluble" refers to a substance that does not dissolve in water. The two substances that are insoluble in water are sand and chalk powder.
 (d) four substances that can be used as filters
Four substances that can be used as filters:
1. A piece of muslin cloth
2. Filter paper
3. A bead of sand
4. Charcoal.
Explanation:
1.The filtration procedure separates the solid particles from the liquid.
2. Filter paper has microscopic holes in it that trap the insoluble particles.
3. The filtrate is the liquid that has been reclaimed after passing through filter paper.
4. The muslin cloth has the potential to remove viruses linked to the particles in this case.
The suspended stuff in the liquid is removed by a sand layer in the filter.
5. Activated carbon (charcoal) is good at eliminating chlorine, volatile organic compounds, and other contaminants.

Note :
Don't get the terms sublimation and deposition mixed up. Sublimation is the process by which a solid transforms into a gas or vapour without becoming a liquid, whereas deposition is the process by which a gas or vapour transforms into a solid without becoming a liquid.
