Test for nitrates (NO3)  soluble salt

Equipment

  • Nitrate test paper
  • Distilled water
  • Dropper

I put two drops of distilled water on the jar and then put the test strip (nitrate test paper) on the jar and held it there for about a minute.  The color changing means that there are nitrates in the jar.

The test strip shows a postive result.

The test strip shows a negative result.
