Hello all, my first post :). Right, I have to calculate the percentage error of my Iron tablet Redox titration. On the biuret it said +-0.05! Now I am wondering, because I took two measurements from the biuret; one when I put the titre in until it was at 0, and then another when the reaction had occurred. So, wouldn't I have to multiply the variable (+-0.05) by 2? Any help would be greatly appreciated, thank you for taking the time to read my problem :)
