A chemical formula is a picture of the molecule, a representation of its structure.

The arrangement of the atoms in space is the true key to understanding the properties of chemical compounds.

Stereochemistry is the chemistry of space.

The tetrahedral carbon atom is the foundation of organic chemistry.

Imagination is necessary for the discovery of new truths.

Science is built up of facts, as a house is built of stones; but an accumulation of facts is no more a science than a heap of stones is a house.

The more we know, the more we realize how much we don't know.

The laws of thermodynamics are the most fundamental laws of nature.

Chemical affinity is a measure of the work that can be obtained from a chemical reaction.

The rate of a chemical reaction is proportional to the product of the concentrations of the reacting substances.

Osmotic pressure is a colligative property, dependent only on the number of solute particles, not their nature.

Solutions behave like gases, and osmotic pressure is analogous to gas pressure.

The van 't Hoff factor accounts for the dissociation of electrolytes in solution.

Physical chemistry is the bridge between physics and chemistry.

The future of chemistry lies in the application of physical principles.

The study of chemical equilibrium is essential for understanding chemical reactions.

The principle of mobile equilibrium states that a system at equilibrium will respond to a disturbance in a way that counteracts the disturbance.

The temperature dependence of equilibrium constants is described by the van 't Hoff equation.

The Nobel Prize in Chemistry is a great honor, but the greatest reward is the joy of discovery.

Science is an international endeavor, transcending national boundaries.
