Which of the following statements regarding emulsions is false?a)Emuls...
Emulsions are a type of colloidal dispersion in which two immiscible liquids, typically oil and water, are mixed together to form a stable mixture. The emulsion is composed of small droplets of one liquid dispersed throughout the other liquid. Emulsions have a wide range of applications, such as in food, cosmetics, and pharmaceuticals.

The statement that is false regarding emulsions is:

a) Emulsions cannot be separated into their constituent liquids.

Explanation:

Emulsions can indeed be separated into their constituent liquids through various methods. Some common separation techniques include:

1. Gravity separation: Emulsions can be left undisturbed for a period of time, allowing the lighter liquid to rise to the top and the heavier liquid to settle at the bottom. This process is known as creaming or sedimentation, and it can be used to separate the two liquids.

2. Centrifugation: By subjecting the emulsion to high-speed rotation in a centrifuge, the centrifugal force separates the two liquids based on their densities. The heavier liquid is forced to the bottom, while the lighter liquid is collected at the top.

3. Heating and cooling: Emulsions can sometimes undergo phase separation when heated or cooled. For example, if an oil-in-water emulsion is heated, the oil droplets may coalesce and rise to the top, allowing for separation.

4. Chemical methods: Various chemicals can be added to emulsions to break them down and separate the liquids. For instance, adding a salt solution can cause the emulsion to destabilize and separate into its constituent liquids.

It is important to note that while emulsions can be separated into their constituent liquids, the process may not always be easy or efficient. Factors such as the stability of the emulsion, the size of the droplets, and the properties of the liquids can all affect the separation process.

In conclusion, the statement that emulsions cannot be separated into their constituent liquids is false. Emulsions can be separated using different methods, such as gravity separation, centrifugation, heating and cooling, and chemical methods.

Similar Class 12 Doubts

Read the passage given below and answer the following questions:The d block elements are the 40 elements contained in the four rows of ten columns (3-12) in the periodic table. As all the d block elements are metallic, the term d-block metals is synonymous. This set of d-block elements is also often identified as the transition metals, but sometimes the group 12 elements (zinc, cadmium, mercury) are excluded from the transition metals as the transition elements are defined as those with partly filled d or f shells in their compounds. Inclusion of the elements zinc, cadmium and mercury is necessary as some properties of the group 12 elements are appropriate logically to include with a discussion of transition metal chemistry. The term transition element or transition metal appeared to derive from early studies of periodicity such as the Mendeleev periodic table of the elements. His horizontal table of the elements was an attempt to group the elements together so that the chemistry of elements might be explained and predicted. In this table there are eight groups labeled I-VIII with each subdivided into A and B subgroups. Mendeleev recognized that certain properties of elements in Group VIII are related to those of some of the elements in Group VII and those at the start of the next row Group I. In that sense, these elements might be described as possessing properties transitional from one row of the table to the next.In the following questions, a statement of assertion followed by a statement of reason is given.

Read the passage given below and answer the following questions:The amount of moisture that leather adsorbs or loses is determined by temperature, relative humidity, degree of porosity, and the size of the pores. Moisture has great practical significance because its amount affects the durability of leather, and in articles such as shoes, gloves and other garments, the comfort of the wearer. High moisture content accelerates deterioration and promotes mildew action. On the other hand, a minimum amount of moisture is required to keep leather properly lubricated and thus prevent cracking. The study indicates that adsorption of moisture by leather is a multi- molecular process and is accompanied by low enthalpies of adsorption. Further at 75-percent relative humidity, the adsorption is a function of surface area alone. Untanned hide and chrome- tanned leathers have the largest surface areas. The leathers tanned with vegetable tanning materials have smaller surface areas since they are composed of less hide substance and the capillaries are reduced to smaller diameters, in some cases probably completely filled by tanning materials. This process of tanning occurs due to mutual coagulation of positively charged hide with negatively charged tanning material. The result of the study indicated that untanned hide and chrome-tanned leather absorb the most water vapour.In these questions a statement of Assertion followed by a statement of Reason is given.
