This web page contains a video clip, animations and student worksheets exploring the dissolving of ionic solids in water. The video clip has both filmed and animated scenes that compare the dissolving of sodium chloride with melting and show how the dissolving process can be represented by chemical equations. Important ...

This web page contains ten animations of molecules and compound ions as well as nine QTVR objects showing organic molecules. The animations rotate the molecules to show their structure fully. The QTVR objects can be manipulated by the user so that, as well as being rotated, different ways of modelling the molecules can be seen.

This web page contains a video, animations and a student worksheet examining the proton-transfer reactions of acids and bases. Self-ionisation of water, acidity of hydrated metal ions, proton gain by ammonia molecules and proton loss from acetic acid are depicted. The animations show important molecular-level segments from ...
