The most common substance that dissolves in water is probably salt.
Oceans, which cover nearly 70% of Earth's surface, are salt-water
solutions. On this page, you will learn how salt dissolves in water.
First, let's take a look at the chemical structure of salt.

The image to the left shows a close-up view of some grains of salt
in water. We will focus in on the right side of a grain of salt as
it interacts with the surrounding water. The interactive below shows
a microscopic view of what happens at the salt-water interface.<br><br>The
red atoms represent oxygen and the white ones hydrogen.
