Chapter 1: Problem 76

Classify the following mixtures as homogeneous or as heterogeneous. a. potting soil d. window glass b. white wine e. granite c. your sock drawer

Short Answer

Expert verified
a. Potting soil: heterogeneous b. White wine: homogeneous c. Your sock drawer: heterogeneous d. Window glass: homogeneous e. Granite: heterogeneous

Step by step solution

01

Mixture a: Potting soil

Potting soil is a mixture of various organic and inorganic materials like peat, sand, perlite, compost, and other nutrients. These different components can be seen and are not evenly distributed throughout the mixture. Therefore, potting soil is a heterogeneous mixture.
02

Mixture b: White wine

White wine is made by fermenting grape juice, which is a mixture of water, alcohol, sugars, and other organic compounds. Although it is a mixture, its composition is uniform throughout the liquid, with no visible distinct phases. Therefore, white wine is a homogeneous mixture.
03

Mixture c: Your sock drawer

A sock drawer typically contains socks of various sizes, colors, and materials. These differing socks can be seen and are not evenly distributed throughout the drawer. Therefore, your sock drawer is a heterogeneous mixture.
04

Mixture d: Window glass

Window glass is made primarily of silica, with small amounts of other materials such as sodium carbonate and calcium oxide. Although it is made of multiple components, these elements are mixed and fused together during production, resulting in a uniform composition with no visible distinct phases. Therefore, window glass is a homogeneous mixture.
05

Mixture e: Granite

Granite is a type of rock composed of interlocking mineral crystals, such as quartz, feldspar, and mica. These minerals are visibly distinct from one another and not evenly distributed throughout the rock. Therefore, granite is a heterogeneous mixture.
