Reactivity of Halide Ions Purpose: There are four halide salts used in this experiment that are found in the human body. Sodium fluoride is poisonous‚ but has been traced to be beneficial to humans in the prevention of tooth decay. Sodium chloride is added to many of our foods to increase flavor. Sodium chloride is important for many life processes‚ but too much intake is linked to high blood pressure. Sodium bromide is distributed throughout body tissues. Sodium iodine controls cell growth.

study of eyewitness testimony (EWT) was by Loftus and Palmer. Their aim was to see whether asking leading questions had any effect on recall. The method used was a laboratory experiment and had two parts to it. The first was showing participants (Ppts) 7 films of car accidents. Participants were then asked questions‚ including “How fast were the cars travelling when they **** each other?” The asterisks were then replaced with a different verb‚ including “smashed” and “hit.” The second part of the
