Lahvanya Raoov added Describe chemical tests for water using cobaltII chloride and copperII sulfate to To do. What is the chemical use to test water. Test strips These are small single-use strips that change color to indicate the concentration of a specific chemical.
In the lab review the field instructions on how to conduct each of the six tests on practice water. Anhydrous copper sulphate Describe how rainwater can be an agent of chemical weathering. Water dissolves the rocks Is formation of water when hydrogen burns.
Divide the class into groups of 3-4 students. Depending on the particular test the user activates the paper or plastic strip by dipping it into the water sample and swishing it around. In a hard water sample the total hardness can be determined by titrating the Ca 2 and Mg 2 present in an aliquot of the sample with Na 2 EDTA solution using NH 4 Cl-NH 4 OH buffer solution of pH 10 and Eriochrome Black-T as the metal indicator.
