Question

A sample of seawater consists of water, sodium ions, chloride ions, and several other dissolved salts. These ions and salts are evenly distributed throughout the water.
Which term or terms could be used to describe this sample of seawater?
a. Mixture
b. Heterogeneous mixture
c. Homogeneous mixture
d. Solution
e. Pure chemical substance
f. Compound
g. Element

Answer 1

Answer:

The correct option is c

Explanation:

An homogeneous mixture is a mixture (either solid, liquid or gas) in which the constituents of the mixture are evenly distributed. Examples are pure sample of air, salt solution and sugar solution. Homogeneous mixture can be explained from the example given in the question; if 5 ml sample of a sea water is collected, the quantity of water, sodium ions, chloride ions and other dissolved salts will be equal in each 1 ml of the sample. This means the water, ions and salts are equally distributed.

When they are not equally distributed, it is known as heterogeneous mixture. Generally, a mixture is a combination of two or more substances that are not chemically combined or are physically combined.
