Assume that you are right-handed and are performing a titration with a burette. For proper technique, you should be using O a. your left hand to control the stop-cock, making sure the stop-cock is on the same side as your dominant hand. O b.your right hand to control the position of the stop-cock, keeping your left hand free to swirl the Erlenmeyer flask. O. both hands to control the stop-cock position, and you must position your line-of-sight at 45 degrees to the burette. O d. both hands to carefully control the position of the stop-cock because you want to ensure that you do not miss the endpoint of the titration.
