Re: Old Chemistry

I am resurrecting this old thread because those interested in the subject may like to know that that an old book, first published in 1960, has been made available free of charge on the Internet.'The Golden Book of Chemistry Experiments' can be downloaded from http://tinyurl.com/6j84c9

It is about 28Mb long and at 114 pages, rather too long to print, but is a fascinating picture of what chemistry was like at that time.

Re: Old Chemistry

Brian some thoughts on your thread. As I recall the old School Certificate Chemistry papers these old names figured in the first or second questions in the 'A' Section of the exam.
There is a medical museum in Leeds, wll worth a visit, to which someone has given his collection of old Chemist's porcelain containers, quite beautiful and patterned and the name of the contained compound printed in Latin. Contributors naming Aqua Regis, etc reminded me of this.
Concerning the Chemistry paper, I got a credit ( to my surprise ) but some 40 years later I was unable to make any sense whatsoever of my son's GCSE paper.
I also recall Stoker advising us we would be asked for the preparation of Nitrous Oxide and that the equation was worth ten marks and we would also be asked about the commercial production of Ammonia. This was based on his vastly experienced analysis of previous years papers and does show how the subject had become fossilised to some extent. He was correct in both cases. Was this cheating??
I also recall the Chemistry text book had a picture of a boy who had grown a quite huge Alum crystal. The girls here in the Philippines use the crystal alum to deodorise their armpits after sweating.

Re: Old Chemistry

Yes Arthur, I am aware of the Museum in Leeds, but not been there. You also get some old 'chemist' vessels turning up on programmes like 'Antiques Roadshow' and the like.
Aluminium salts seem to be present in most 'deo' formulations, even modern ones. 'Mum' for example contains Aluminium Zirconium Pentachlorohydrate, others Aluminium Chlorhydrate. There was however some concern in the chemical press a while ago that Aluminium salts may have a contributory factor in breast cancer, yet they are still being widely used.
Alum was also used in those sticks you could get to prevent bleeding if you cut yourself shaving

Is the Birmingham district, Alum Rock, the source of Styptic Pencils then?

Re: Old Chemistry

I believe, Arthur, that Stoker was an examiner for JMB Chemmy which may account for his success as a tipster.

Re: Old Chemistry

That will explain it Terry.
At the same time Scratcher Marsden always gave you two maps in his geography end of term examination. He had these mimeoed and brought to his room. I was sat at my desk at the front of the class when they were brought to him. Very slowly he went to his cupboard with the maps fully evident paused in front me and looked down at the maps and looked me in the eyes. I looked at the maps and recognised India. He waited and then slowly opened the cupboard and placed them inside. Soon all the school knew one of the maps later the word went round that the other was Russia in Europe so he must have played the game with another class. Both maps were in the exam.
One way of getting good exam results I suppose.

Re: Old Chemistry

Just going back to Arthur's comment about nitrous oxide. One of the most difficult chemical equations to 'balance' was in fact the preparation of Nitric Oxide(NO) (not Nitrous N2O) - sorry cant be bothered with subscripts.
It was the reaction of copper with 50% strength Nitric acid (You got different results with weaker or stronger acid) Here goes:-

3Cu + 8HNO3 = 3Cu(NO3)2 + 4H2O + 2NO

But you never actually saw the NO because it immediately oxidises further with oxygen in the air to give brown fumes of Nitrogen Dioxide (NO2), the latter very poisonous.

Re: Old Chemistry

Joke!Element Name. WOMAN.
Symbol:WO
Atomic Weight:don`t even go there
Physical Properties:Generally round in form.Boils at nothing and may freeze at any time. Melts whenever treated properly.Very bitter if not used well.
Chemical Properties.Very active. Highly unstable.Possesses strong affiniy to gold,silver,platinum,and precious stones. Violent when left alone.Able to absorb great amounts of toxic food. Turns slightly green when placed next to a better specimen.
Usage:Highly ornamental. An extremely good catalyst for dispersion of wealth .Probably the most powerful income-reducing agent known.
Caution:Highly explosive in inexperienced hands.

Re: Old Chemistry

JOKE
Element Name:MAN
Symbol: MAN
Atomic Weight:180+/50
Physical Properties:Solid at room temperature,but gets bent out of shape easily.Fairly dense and sometimes flaky.Difficult to find a pure sample.Due to rust,ageing samples and unable to conduct electricity as easily as young samples.
Chemical Properties: Attempts to bond with WO any chance it can get . Also tends to form strong bonds with it.Becomes explosive when mixed with Kid Element:Child- for prolonged period of time.
Neutralize by saturating with alcohol.
Usage:None known.Possibly good methane source. Good samples are able to produce large quantities on command.
Caution:In the absence of WO,this element rapidly decomposes and begins to smell.
