Mercury Chloride 3. Determine the oxidation number for the indicated element in each of the following compounds or ions: (0 points) a. Mn in Mnoe b. Na in NaH c. Pin PO42. Answer: d. N in NH4 Answer: Cr in Cryo,2- e. f Fe in FeCl C in Hrco h. O in OF2 i. S in Sno, j, H in MgH MacBook AirExplanation / Answer
1. Classification of compounds as follows
Strong electrolytes completely ionize in water like strong acids and strong bases. Weak electrolytes partially ionize in water. If a substance doesn’t ionize in water at all, it’s a non-electrolyte.
2. Water soluble compound at room temperature
All chlorides, bromides and iodides are soluble EXCEPT those of silver, lead and mercury(I)
All sulfates are soluble EXCEPT those of silver, lead, mercury(I), barium, strontium and calcium.
Carbonates, sulfites and phosphates are insoluble EXCEPT Ammonium
3. Oxidation number as follows
