Consider the following chemical emulsions.1. Pentadecanol2. Hexadecano...
Explanation:
To minimize the loss of water through the process of evaporation, emulsions can be used. Emulsions are mixtures of two or more immiscible liquids, where one liquid is dispersed in the form of small droplets within the other liquid. The dispersed phase is typically an oil or a hydrocarbon, while the continuous phase is usually water.
Among the given options, the emulsions that can be used to minimize the loss of water through evaporation are:
1. Pentadecanol: Pentadecanol is a long-chain alcohol with 15 carbon atoms. It is commonly used as an emulsifying agent in various industries, including cosmetics and personal care products. As an emulsion stabilizer, it can help prevent the evaporation of water by forming a protective barrier on the water surface.
2. Hexadecanol: Hexadecanol is another long-chain alcohol with 16 carbon atoms. Like pentadecanol, it is used as an emulsifying agent and can help reduce water loss through evaporation. It forms a film on the water surface, which acts as a barrier and slows down the evaporation process.
3. Octadecanol: Octadecanol is a long-chain alcohol with 18 carbon atoms. Although it is a good emulsifying agent, it may not be as effective in minimizing water loss through evaporation compared to pentadecanol and hexadecanol. It can still provide some level of protection, but it may not be as efficient as the other options.
4. Kerosene: Kerosene is a hydrocarbon liquid that is commonly used as a fuel. While it can form emulsions with water, it is not typically used for minimizing water loss through evaporation. Kerosene is more commonly used as a solvent or fuel rather than an emulsion to reduce water evaporation.
Therefore, the correct answer is option 'D' - 2 and 3. Both hexadecanol and octadecanol can be used to minimize the loss of water through evaporation. Pentadecanol can also be effective in this regard, but it is not included in the given options. Kerosene, on the other hand, is not primarily used for this purpose.
