drinking water? Saltwater is becoming a problem to our drinking water because it is getting into the rivers that we get our drinking water from and it and the saltwater it is also intruding aquifers. The place where you can see the most change is in Florida because of the climate change. Because whenever it floods in Florida the seawater gets into the rivers and also seeps into the grounds. When it seeps into the ground it gets into the aquifers and that’s how Florida is losing its water. It is also

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
