Interactive exploration Chemistry & Materials Acids, bases and the pH scale Why is one step on the pH scale a big change? Compare a hundredfold difference, transfer a tiny aliquot, turn a virtual burette and uncover why a weak acid and a strong acid reach different pH values at equivalence.

Interactive exploration Chemistry & Materials Atoms and chemical elements What makes carbon different from oxygen? Change particle counts, pin the differences, and discover what names an element. Then prepare one-electron hydrogen states, collect possible position outcomes and match energy gaps to light.
