Chapter 2: Q118P (page 85)

Is a solution a homogeneous or a heterogeneous mixture? Give an example of an aqueous solution.

Short Answer

Expert verified

The solution is a homogenous mixtureand an exampleNaCIis an aqueous solution.

Step by step solution

01

Difference between homogeneous and heterogeneous mixture

In a homogenous mixture, the components are uniformly distributed while in a heterogenous mixture the components are not uniformly distributed.

02

Aqueous solution

From the definition, we can say that solution is a homogeneous mixture as in a solution the components are perfectly mixed for example on mixing salt () in the water we get a homogenous mixture or a solution.

Samples of illicit 鈥渟treet鈥� drugs often contain an inactive component, such as ascorbic acid (vitamin C). After obtaining a sample of cocaine, government chemists calculate the mass of vitamin C per gram of drug sample, and use it to track the drug鈥檚 distribution. For example, if different samples of cocaine obtained on the streets of New York, Los Angeles, and Paris all contain 0.6384 g of vitamin C per gram of sample, they very likely come from a common source. Do these street samples consist of a compound, element, or mixture? Explain.
