I taught chemistry for 25 years. I now provide tuition online. I just like nicely produced, imaginative resources. (NB &1.00 is the lowest price that I can charge for my resources, that have an unlimited license. For each £1.00 sale I receive £0.35)

Disappearing cross plus gas syringe simulations. Please note: in order to provide a rich interactive experience, my interactive resources are mini-web sites local to your computer. After unzipping, they comprise a folder containing the main .html file and another folder containing the graphic resources and my coding to make the resource work. Double click on the .html file and the resource will work. If, however , you move or delete any of the files from this hierarchy, the resource will not work. stdobbs.com ©D&D production

I have tried to produce a clear example of an acid/base titration for use on the board or as a handout. I used colour to make it as clear as possible.

Quick and short presentation on how to balance the manganate (vii) half equation, to save you time. I have now added the oxidation of ethanol by acidified potassium dichromate (VI) as another example.

Word searches help concentrate on scientific literacy and aid concentration. they are good summary activities and for revision. I have tried to make this attractive and efficacious in that it uses only one side of A4. A solution is provided.
Neutralisation Reactions

Neutralisation Reactions

This is a simple worksheet about writing word equations for neutralisation reactions. It covers 2 pages. There are plenty of examples, which get harder as you go on. There is an accompanying powerpoint, as an additional download… NB I am well aware that exam boards, RSC and text books regard acid plus metal to be a redox reaction, which of course it is. However, in such a reaction, the pH increases to neutral and the acid has gone, so I think it can properly be regarded as neutralization of an acid. And since this worksheet is really about naming salts, I had to include it.

I made a very simple ‘fill in the gaps’ worksheet. It may be useful because it focuses on the adjectival and noun words in this topic.
