EXPERIMENT 5 REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE Objectives 1. 2. To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. To acquire the proper techniques of carrying out a titration. Introduction Redox titrations using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The reaction involved is: I2 + 2Na2S2O3 I2 + 2S2O322NaI + Na2S4O6

Produced by cell clusters in the pancreas called the Islets of Langerhans‚ insulin is a hormone that regulates glucose concentration in the blood. It is a protein synthesised and stored by beta cells‚ which secrete it in surges responding to changes in glucose levels. (Hardin‚ Bertoni and Kleinsmith‚ 2012) Fig 1.

The environmental problem I chose in my local area of Pennsville‚ New Jersey is the pollution of our water sources. The impact of the industrial discharge‚ pesticides‚ atmospheric deposition‚ and urban street run off is causing depleted oxygen levels‚ our fish to test positive for Polychlorinated Biphenyls (PCBs)‚ aquatic life impairment of Phosphorous and Total Suspended Solids (TSS)‚ Nitrogen contamination‚ and primary contact recreation to be contaminated by Enterococcus Bacteria and Fecal Coliform

Weigh boats which are called filter paper can be utilized as transporting vessel of the chemical to be measured. Filter papers are classified as low-cost version of the weigh boats. The material makeup of weigh boats or filter papers is polypropylene‚ a plastic that does not adsorb water (Thinkwell‚ 2012). (d) (2 pts) According to the lab video‚ what is the difference in how
