A colorless solution is known to contain one of these ions. Which ion is present if adding dilute HCl produces a white precipitate that dissolves when the solution is warmed?
The Attempt at a Solution
The only one I could really rule out was copper chloride, as it is soluble. I'm stuck because I know that AgCl, Hg2Cl2, and PbCl2 are all white precipitates. Without using a chart, how can I determine qualitatively which dissolves in a warmed solution? Thank you in advance.
