Chapter 2: Q. 2.8 P (page 81)

The tap water found in many areas of the United States leaves white deposits when it evaporates. Is this tap water a mixture or a compound? Explain.

Short Answer

Expert verified

Tap water is a mixture as it contains water with some dissolved chemicals such as calcium or magnesium carbonates and sometimes fluorides.

Step by step solution

01

Mixture 

Mixtures are made by mixing two different components physically not in a fixed ratio.

02

Why tap water is a mixture 

Given that white substance is deposited on evaporation of water it shows that the tap water has calcium as a dissolved mineral in it.

So we can say that tap water is a mixture as it contains water with some dissolved chemicals such as calcium or magnesium carbonates and sometimes fluorides.
