Experimental uncertainty arises because of: Limits in the how exact the measuring apparatus is. Maximum Percentage Error When I finish my titration the volume reads 35.6cm3.” “The volume I used in the titration is 12.4cm3 (48cm3 – 35.6cm3)” “I took two reading from the burette therefore my uncertainty Percentage errors!??? or can the Mods just move it Last edited by Couldxbe; 13-03-2007 at 19:39.
