Chapter 1: Problem 3

Fog is a suspension of tiny droplets of water in air. Is fog a heterogeneous mixture or a homogeneous mixture? Explain.

Short Answer

Expert verified
Fog is a homogeneous mixture. This is because the tiny droplets of water are evenly distributed in the air, providing a uniform appearance. Although fog consists of two components (water and air), the particles are small and dispersed, making it appear as a single substance.

Step by step solution

01

Understand the definitions of heterogeneous and homogeneous mixtures

A heterogeneous mixture is a mixture where the components remain distinct and can be visibly separated, like sand in water. A homogeneous mixture, on the other hand, is a mixture where the components are uniformly distributed, and it appears as a single substance, like salt in water.
02

Classify fog

Fog is a suspension of tiny droplets of water in air. It appears uniform to the naked eye, as the droplets are small and evenly distributed. Therefore, fog is a homogeneous mixture.
03

Support our classification with an explanation

To explain our classification, we can state that fog is a homogeneous mixture because even though it consists of two components (water and air), the particles of water are tiny and distributed uniformly throughout the air, giving it an even appearance.
