Which of the following describes a product that is diluted?

A product that is diluted refers specifically to the process of reducing the concentration of a substance by mixing it with another substance, typically a solvent such as water or oil. In the context of product usage, "diluted" indicates that the original formulation has been modified to lower its potency or concentration, making it more suitable for certain applications.

When a product is mixed with water or oil, it alters the original product's strength. For example, in cleaning solutions or certain chemicals, dilution makes them safer or more effective for use. Understanding this concept is crucial for maintaining proper concentrations for safety and efficacy in various applications.

The other options do not accurately define dilution; mixing with an emulsifier pertains to combining two immiscible liquids, storing a product does not affect its concentration, and describing a product as concentrated directly opposes the concept of dilution.
