The conclusion of testing the hardness and presence of the iron, fluoride, and chloride can be identified by solution in pale green color, solution turning to colorless, and a white precipitate forming in the solution.

Explanation:

  • To test the presence of iron in the solution, the sodium hydroxide test is done and finally due to the presence of the iron ions, the entire solution will turn to a pale green color.
  • to test the presence of fluoride, a color test kit is used which is dipped in the solution and after 60 seconds, the color of the solution will turn into colorless.
  • To test the presence of chloride ions, the silver nitrate test is used where the white precipitate forms in the solution.
