  • Chemistry Sets
    I had a basic chemistry set from Merit in the mid to late 1960s, but my favourite was a massive chemistry set from Waddington's. This had lots of chemicals and used sodium bisulphate as a substitute for conc. sulphuric acid, so heating common salt and Sodium bisulphate produced hydrogen chloride which dissolved in water to make hydrochloric acid. This was so exciting!
