Final answer:
To identify pure compounds in commercial products such as toothpaste, soap, and shampoo: toothpaste may contain sodium fluoride, soap often has sodium stearate, and shampoos typically include sodium lauryl sulfate, all of which are compounds. The correct option is A.
Step-by-step explanation:
The question is asking to identify the pure compounds in common commercial products such as toothpaste, soap, and shampoo. First, it is important to define what a compound is in this context. A compound is a substance that is made up of two or more elements that are chemically combined in fixed ratios. For example:
-
- Toothpaste might contain sodium fluoride (NaF) as a compound for preventing cavities, among other compounds.
-
- Soap often contains sodium stearate, a type of salt derived from stearic acid, as a compound.
-
- Shampoo typically includes lauryl sulfate compounds such as sodium lauryl sulfate (SLS) for creating lather.
These examples highlight some of the pure compounds that can be found in each product. However, it's important to note that many commercial products also contain mixtures of compounds and additional ingredients that are not pure compounds.
