⇒ Nitric acid is used in explosives and in the making of fertilizers.

 

Common bases and their uses:

⇒Sodium hypochlorite (NaClO) - sodium hypoclorite is the common ingredient in the household bleach.  

⇒Sodium hydroxide (NaOH): This base is commonly used as oven, drain and lye cleaner

⇒Aluminum hydroxide (Al[OH]3): Aluminium hydroxide is an active ingredient in deodorants and antacids.

⇒Magnesium hydroxide (Mg[OH]2): This base is also used in antacids and as a laxative.

⇒Calcium hydroxide (Ca[OH]2) is used in  mortar, caustic lime and plaster.

⇒Sodium carbonate (Na2CO3) is used as a dish detergent

⇒Ammonium hydroxide (NH4OH) is used as a glass cleaner.
