The existence of ions in solution was a radical departure from the prevailing views of the time.

The properties of dilute solutions are largely independent of the nature of the solvent, as long as it is a good dissociating medium.

The concept of 'active mass' in chemical kinetics is directly related to the concentration of reacting species.

The study of reaction rates provides a window into the molecular mechanisms of chemical change.

The earth's atmosphere acts as a selective filter for solar radiation, allowing some wavelengths to pass through while absorbing others.

The greenhouse effect is a natural phenomenon, but human activities are intensifying it.

The amount of water vapor in the atmosphere is also a crucial factor in regulating the Earth's temperature.

The long-term consequences of industrialization on the global climate are a matter of scientific concern.

The universe is not static; it is constantly evolving and changing.

The concept of 'absolute zero' is a theoretical limit that can never be reached in practice.

The progress of science often depends on challenging established paradigms.

The scientific method, based on observation and experimentation, is the most reliable path to knowledge.

The future of humanity is intertwined with our understanding of the natural world.

The theory of electrolytic dissociation is the key to modern chemistry.

Any acid is a substance which yields hydrogen ions in solution, and a base is a substance which yields hydroxyl ions.

Human activities are causing an increase in atmospheric carbon dioxide, which will lead to a warming of the Earth's surface.

We are evaporating our coal mines into the air.

By the influence of the increasing percentage of carbonic acid in the atmosphere, we may hope to enjoy ages with more equable and better climates, especially as regards the colder regions of the earth.

The enormous combustion of coal by our industrial establishments suffices to increase the carbon dioxide in the air to a perceptible degree.

The world's present production of coal reaches in round numbers 500 millions of tons per annum, or 1 ton per square kilometer of the earth's surface.
