I am trying to understand the relationship between activation energies of strong and weak acids when they react with metals. Why do strong acids have lower activation energies than weak acids?
• I am investigating the acid content in wines by performing a titration with sodium hydroxide. I know Ill have to dilute my wine sample with distilled water and add phenolphthalein to determine the amount of tartaric acid in my sample, but I’m wondering is this the best way to carry out the investigation? • I have used colorimetry to find the concentration of manganese in tea by comparing the results with different concentrations of potassium manganate(VII) solution. I used the following method to extract the manganese from the tea: Strongly heat the dry tea to give a white ash. Add 15 cm3 distilled water, 3 cm3 concentrated sulphuric acid, 4 cm3 85% phosphoric acid, 8 cm3 concentrated nitric acid, and boil. Then add 50 cm3 0.01M silver nitrate solution and 2.5g ammonium peroxodisulphate, and boil to give purple solution. I wanted to know what reactions are taking place when each different chemical is added. Thanks. • I am doing a titration for the sugar content of wine and using Quan
