Which of the following statements is true for synthetic detergents?
Synthetic detergents are more effective in hard water than soaps.
Synthetic detergents are biodegradable and environment friendly.
Synthetic detergents are made up of sodium salts of long-chain fatty acids.
Synthetic detergents are less soluble in water than soaps.
Synthetic detergents are compounds that are produced using synthetic or artificial means. They are typically made from petroleum products, which are not biodegradable and are harmful to the environment. However, many synthetic detergents are now made from biodegradable materials.
One of the advantages of synthetic detergents over soaps is that they are more effective in hard water. Hard water contains high levels of minerals such as calcium and magnesium, which can react with the fatty acids in soap to form a scum. This scum reduces the effectiveness of soap in cleaning. Synthetic detergents, on the other hand, are not affected by hard water and can clean effectively in both hard and soft water.
Option B is incorrect as not all synthetic detergents are biodegradable and environment-friendly. Option C is incorrect as it refers to soaps, not synthetic detergents. Option D is also incorrect as synthetic detergents are more soluble in water than soaps.
