Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

The negative logarithm is a convenient way of expressing the magnitudes of other small
quantities. We use the convention that the negative logarithm of a quantity is labeled

The pH and pOH values characteristic of a number of familiar solutions are shown in
(V Figure 16.6). Notice that a change in [H*] by a factor of 10 causes the pH to change by 1.
