The reaction is done with potassium manganate(VII) solution and hydrogen peroxide solution acidified with dilute sulphuric acid. 1) ASTM 317L, e.g. I think probably that was the beginning of real experimentation in chemistry. Risk (Severe risk) of stress corrosion cracking. Sandvik 3R642) EN 1.4439, e.g. The potassium permanganate was a premade solution obtained from a supplier. The colour change depends on whether the potassium manganate (VII) is used under acidic or alkaline conditions. Ah my apologies, I assumed this was right as my teacher had written these. In the weak acid (such as acetic acid), potassium permanganate fades slowly. 2) The charges cannot disappear in chemistry. Thanks for contributing an answer to Chemistry Stack Exchange! These corrosion data are mainly based on results of general corrosion laboratory tests, carried out with pure chemicals and water solutions nearly saturated with air (the corrosion rate can be quite different if the solution is free from oxygen). The same error occurs in your first equation ! Once the permanganate dissolved in the sulfuric acid, you will be able to see spark appearing in the layer of ethanol. (Used only where there are no actual data to estimate the risk of localised corrosion instead of p or s). In your second equation, you have a total of 6 positive charges at the left-hand side, and no charges at all at the right-hand side.
