here are the observations and inferences for the question: 1. Observation 1: A white precipitate forms upon the addition of sodium hydroxide solution. Inference 1: This indicates the presence of metal cations that form insoluble hydroxides. Examples include Zn^2+, Al^3+, Pb^2+, Mg^2+, Ca^2+, etc. 2. Observation 2: The white precipitate dissolves in excess sodium hydroxide solution, forming a colorless solution. Inference 2: This specifically points to the presence of amphoteric metal ions, which can react with both acids and strong bases. The common amphoteric ions that form white precipitates soluble in excess NaOH are Zn^2+, Al^3+, and Pb^2+. What's next? 📸
