Chemicals in the Home - Part A

 

Part A -- Part B -- Part C -- Part D -- Part E -- Part F -- Part G

 

The substances or solutions shown in a-h are to be reacted during the course of this experiment.  For each: i. predict chemical formulas for all products, ii. write a balanced chemical reaction (not in words!), and iii. predict what should be observed experimentally (colorless gas evolved, precipitate formed, ammonia smell, etc.).

 

a. solid smelling salts and aqueous sodium hydroxide
(Note: Ammonium hydroxide, NH4OH, does not exist in solution but decomposes to gaseous ammonia and water.)
