you have one test tube which contains a solution that is either zn 2(aq) or mn 2(aq). select a reagent that will allow you to differentiate between the two chemical species. if the solution is zn 2(aq), what will happen when the reagent is added? if the solution is mn 2(aq), what will happen when the reagent is added?



Answer :

NaOH can be used to differentiate between the two chemical species.

  • The determination of non-numerical information about a chemical species, a reaction, etc. is known as qualitative analysis.
  • Examples include seeing that a reaction produces gas that is popping out of solution or that a reaction causes a change in hue.
  • Although qualitative analysis is frequently much simpler, quicker, and less expensive than quantitative analysis, it is not as trustworthy.

(a) If it is Zn+2(aq), the colorless solution will stay colorless after adding the NaOH.

(b) If it is Mn+2(aq), a pale pink precipitate will form after adding the NaOH.
