Question

EXPERIMENT 1: Part VI: Qualitative Analysis of Unknown 2 Record your observation for unknown 2 and submit them as data sheet unknown 2 based the course schedule. Add more Rows if needed! Part added observation reagent chemical reaction soluble precipitate Write a rationale explaining how you determined which cations are absent and which are present. Rational must explain stepwise how the observations prove the presence (or absence) of a cation. Summary data: List of all ions present List of all ions absent What do you know about your unknown if no precipitate forms after adding 6 M NaOH solution?
