Assuming that 0.5 grams of a 1.0 gram sample is CaCO3, what should the concentration of HCl (M) be if you want to use 25.0 mL for the titration
In lab we are doing chemical kinetics. We started off with 0.7550 M of Oxalic acid and then added water and 0.1300 M of Permanganate. For the first trial, 5 mL of Oxalic acid was used, then 6 mL of water were added and then 1 mL of Permanganate we..
