48. Select the meaning of the underlined word in this sentence. When something is *diluted*, what is the outcome?

Answer: B

Explanation:

When something is diluted, it makes it weaker.

Dilution refers to the process of reducing the concentration of a substance in a solution, which inherently makes that substance less potent or effective. Therefore, the outcome of dilution is that it makes the solution weaker.

A) Decreases its temperature

This option is incorrect because dilution does not inherently involve a change in temperature. While some dilution processes may have thermal effects, the primary meaning of dilution is related to concentration rather than temperature.

B) Makes it weaker

This option is correct as dilution specifically refers to the process of reducing the concentration of a solution, thereby making it weaker. When a substance is diluted, its strength or potency is lessened.

C) Combines with an acid

This option is incorrect because dilution does not imply a chemical reaction, such as combining with an acid. Dilution simply refers to the addition of a solvent to reduce concentration, without any specific chemical interaction.

D) Creates a sterile field

This option is incorrect as the act of dilution does not relate to the creation of a sterile environment. Sterility involves the complete absence of microorganisms, which is not a direct outcome of dilution.

Conclusion

In summary, the correct answer is that dilution makes a solution weaker, as it involves reducing the concentration of the solute. All other options provided do not accurately reflect the definition or outcome of the dilution process, highlighting the importance of understanding the terminology in chemical contexts.
