I need to name an ionic compound containing a transition metal cation and a halogen anion. Below are the rules I should follow to write the correct name for such compound, but one of the options is incorrect: identify and select it. Select one: a. Identify the metal and write its name first b. Use the periodic table to work out the charge (oxidation number) on the transition metal according to the group in the periodic table c. From the...

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...

5. An unknown salt consists of two types of cations and one type of anion. The possible an- ions include chloride, CI", carbonate, CO,2-, sulfate, SO 2-. The possible cations include Group 1A cations, K* and Na*, and Group 2A cations, Ca2+ and Sr2+. c) To identify the two cations in your unknown, you do a flame test, and to confirm the identity, you use precipitation reactions. By adding H,So, to your unknown, you observe no precipitate. What can you...
