Question

A student obtained the following results from Part 2B of the lab:

X = precipitate form   ;   NP = no precipitate form

Did the student conduct the experiment correctly?

Yes, the student performed the experiment correctly.

No, the student mistakenly added Cu(NO3)2 solution instead of the Mg(NO3)2 solution.

No, the student mistakenly added AgNO3 solution instead of the Mg(NO3)2 solution.

No, the student mistakenly added Fe(NO3)3 solution instead of the Mg(NO3)2 solution.

No, the student mistakenly added NaOH solution instead of the Mg(NO3)2 solution.

Mg(NO3)2 NaCl NP Na2S NP NaOH NP Na2CO3 NP

Explanation / Answer

Yes, the student performed the experiment correctly.

it is the correct answer all other possibilites are impossible because there are precipitation when they are used
