Collections VisChem topic 12: acid-base reactions

TLF ID M008663

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 the video.
