Acids

Comments (0)

These downloadable videos and animations are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to develop ideas relating to the characteristic reactions of acids.

These resources can be used to unpack the complexities surrounding the reactions of acids. Acids only react like acids when dissolved in water. Insoluble reactants remain visible when in excess and insoluble products emerging in the gas state appears as bubbles. Soluble salts go into solution, unseen. The videos explore the need for water, and show the reactions of acids with metals, metal oxides and metal carbonates. The animations give practice at constructing word equations. Questions and atom structure diagrams to accompany these resources are given in the Stuff and Substance package.

These video and animation files form part of the resources in the section Acid in the Stuff and Substance multimedia package, which provides a series of interactive pages that can be used by teachers or students in the classroom.

HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
