Question:

Only 6 M KOH was present in the reagent shelf-there was no 6M NaOH.

Explain what effect this substitution has on the test for the presence of ammonium ion.

Qualitative Analysis of Ions:

Long before the advent of spectrophotometric techniques to analyze solutions containing ions, there was a long established "wet chemistry" methodology to analyze and identify (mostly qualitatively) the presence of specific ions in solution. The method is still sometimes use today when the spectrophotometric methods are not available.
