To find the concentration of ethanol, using the back titration method, why does the wine need to be distilled?
• How do you use volume displacement to determine the volume of a metal? • For my chemistry investigation, I am investigating the molecular formula of two different compounds formed by adding an excess of 0.1M sodium hydroxide to 0.1M copper sulphate in one beaker and adding an excess of 0.1M copper sulphate to 0.1M sodium hydroxide in another beaker. The result is a blue gelatinous solid that is produced in the first beaker and a light blue powdery precipitate that is formed in the second beaker. I was hoping to find out from you if you know any chemistry behind this phenomenon so that I can get a bit more knowledge about my investigation. • I’m currently doing my A2 investigation on the reaction between potassium iodide ions (1.00 mol dm-3) and potassium peroxodisulphate (0.04 mol dm-3), using the iodine-clock method. I’ve got my experimental data, but now I have to find the rate and I am stuck on the first step – finding the concentration. I have no clue in how to work out the conce
