It is important to think through the reactions that are occurring (or not occurring) and determine how you can rule out the presence of a certain metal ion or how you can posi- tively identify its presence. Use the Solubility Table 1 and Appendix 1 of this manual to understand the precipitation réactions that are observed. You need to consider both the anion and the cation that react to form a given precipitate. The color and the general ap- pearance...

Q 1 & 2
1. Sodium ion (Na) and calcium ion (Ca2) produce nearly the same color in a flame test (yellow and yellow-orange, respectively). Describe a way to differentiate between the two using a solution of Na,CO and write the correct balanced equation(s). (Hint: recall the solubility rules for Na ion.) A saturated solution of an unknown solid reacted with AgNO, to give a pale yellow precipitate, and also reacted with Pb(NO), to give a white precipitate. Based on...

Suppose you have an unknown clear, colorless solution. In attempt to identify it, you add NaOH dropwise and find that a white gelatinous precipitate forms, but when more NaOH was added the precipitate dissolved again. To another test tube of the same unknown solution is added AgNO3 dropwise, and a white precipitate forms. What salt most likely comprises the unknown solution? Explain your reasoning.
