Lab Report 3
Background In this lab, we will detect ions in the water. ... Title Water Testing Purpose The purpose of the lab is to detect the presence of certain ions in a solution, tap water, and distilled water using indicators. ... Materials - 11 test tubes - Solutions: - 2 FeSO (Iron Sulphate) - 2 CaCl (Calcium Carbonate) - 1 NH SCN (Ammonia Thiocyanate) - 3 test tubes tap water - 3 test tubes distilled water - Graduated cylinders - Micropipette - Test tube rack - Indicators: - #1 (use in FeSO , CaCl , H O) - #2 (use in FeSO , CaCl , H O) - #3 (use in NH SCN, H O) Procedure A) Collect test tubes B) Fill 3 test tubes with distilled water C) Fill 3 test tubes with tap water D) Fill 2 test tubes with FeSO solution E) Fill 2 test tubes with CaCl solution F) Fill 1 test tube with NH SCN solution G) Squeeze indicator #1 into 1 test tube each of distilled water, tap water, FeSO , and CaCl using micropipette.
