Teacher has asked for acidified KMNO4 8O for organic practical, looking at double bonds. We have always used Br water, so now i have to make up KMNO4. I have instructions to make 0.1M in 4M H2SO4. It seems very strong. Has any of you used it and what strenght??

OK if it is 0.1M potassium permanganate 15.8g in 1L of water then acidified with a few drops of Conc Sulphuric acid.
you dont want to make it up in 4M acid
