Hi,
I want to perform some simple quantitive chemistry to attempt to work out stoichiometry of some reactions and demonstrating conservation of mass. For example generating carbon dioxide by adding acid to calcium carbonate.
I'm looking to purchase in UK a gas syringe, say 200 cm3 capacity, and an accurate balance, say to 200g at 0.1g "resolution".
I have looked online and the cheapest analytical balance I can find is around £250 (I can afford £50) and I can't find gas syringes at all.
Is there a well known supplier of small quantities (i.e. one) of these items?
Thanks
Clive
