What is a confidence level and how would I use it in my rates of reaction coursework?
• I have been following the wine analysis tutorial on your website. However when I tried to decolourize the red wine with activated charcoal it did not work. I put some charcoal in a filter funnel (using a suction pump), but the colour remained. I also tried adding a sample of charcoal and the wine in a beaker and stirring it, however this did not work either. I have now tried using a large filter funnel with cotton wool, plugging the funnel and with lots and lots of charcoal on top of that. Hopefully this will work but I thought I should email you just incase it doesn’t – as I then will have no idea how to use the charcoal to decolourize the wine. • I have recently carried out a practical investigation using magnesium and hydrochloric acid in order to determine activation energy and order of reaction. In my write up I need to include background information. Can you give me advice to what I should include as background information? • I’m doing my coursework on the thiosulpate-acid expt
