![Hardest Trivia Chemistry Practice Test! - Quiz]()
Correct Answer
A.Explanation
Benzene is a nonpolar compound, meaning it does not readily dissolve in water, which is a polar solvent. However, certain substances called surfactants can disperse benzene in water by reducing the surface tension between the two substances. Surfactants have both hydrophilic (water-loving) and hydrophobic (water-repelling) properties, allowing them to create micelles or emulsions that can solubilize benzene in water to some extent. Therefore, the correct answer would be a surfactant or an emulsifying agent.Rate this question:

The role of phosphate in detergent powder is to:
- A.
Control pH level of the detergent water mixture
- B.
Remove Ca2+ and Mg2+ ions from the water that cause the hardness of water
- C.
Provide whiteness to the fabric
- D.
Form solid detergents a phosphateless detergents are liquid in nature
Correct Answer
B. Remove Ca2+ and Mg2+ ions from the water that cause the hardness of waterExplanation
Phosphate in detergent powder acts as a water softener by removing Ca2+ and Mg2+ ions from the water. These ions are responsible for making water hard, which can lead to various issues such as soap scum, reduced lathering, and decreased cleaning efficiency. By removing these ions, phosphate helps to prevent these problems and allows the detergent to work more effectively in cleaning fabrics.Rate this question:
