I am doing my A2 practical investigation on wine. Can you tell me the main chemical reactions which cause white wine to brown as it oxidises?
• I am doing my investigation on activation energy of the reaction between metal + acid. I used 0.05 M HCl and H2S04 and 0.5 g Mg granules and I recorded how much gas was given off every 10 seconds. Can you help me please, I am trying to figure out how to plot my graph or what to do next. Do I plot a graph for each temperature ? If yes, what do I plot against the other? 260308 • For Mg + acid reactions does agitation affect the rate of reaction or activation energy if you do it consistently? Secondly, what effect does the addition of sodium chloride have when it is added with a strip of magnesium and HCl ? 260308 • Why does the addition of saturated sodium chloride solution to the reaction between HCl and magnesium lower the rate of reaction/increase the activation energy? • Are there any reducing sugars in vinegar? • Hi, I’m conducting a peroxide value experiment on oil and I have some things that I do not really understand. 1. For our experiment, we added 18 ml of acetic acid and 12
