A simple animation to jazz up ionic bonding a little: covers sodium fluoride, magnesium fluoride and lithium oxide. Short and sweet. Just double click on ionic bonding.html and it will run in your web browser. If it’s too small, just zoom in with browser controls. A preview can be seen at on my web site. 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

identify the homologous series from the structural formula

I made a very simple, very introductory presentation on redox reactions. It is intended to be totally entry level.

I recently downloaded the RSC’s very useful “education in chemistry” resource on titrations. The documents are beautifully produced, but I was appalled that the “diagram” column in the equipment tables were low resolution bitmapped graphics. I thought I would produce my own simple diagrams in vector form, so that they can be used at any scale without pixellation. I provide this as a pdf which you can copy and paste from freely, but if you need SVG files , please feel free to contact me via my web site. They may be of use to someone, somewhere.

there are many diagrams of the fractionating column out there. I unashamedly drew on many of them as inspiration for this. However, they are almost exclusively low resolution, bitmapped graphics. I have made my version as an infinitely scalable vector graphic. I then used it to make this labelling exercise. Just for the love of it really. I hope someone might find it useful.

may be useful as a starter or something.

Just for fun, I made this simple revision resource
