Homework Help: Sodium hydroxide neutralized by phosphoric acid

  1. Mar 21, 2005 #1
    The book that I have goes into very little detail about how to do these sort of problems. I know that you have to balance the equation at the end, which I can do. I do not know how to find the elements! :cry: (Besides the fact that Sodium Hydroxide is NaOH.) Can anyone help? THNX! :biggrin:

    a. What salt is formed when a solution of sodium hydroxide is neutralized by phosphoric acid, H3PO4?

    b. What is the equation of this process?

    Rules for Acid-Bases:

    ACID + BASE --> NEUTRAL (or METAL SALT) + WATER
    ACID + CARBONATE --> METAL SALT + CARBON DIOXIDE + WATER
    ACID + REACTIVE METAL --> METAL SALT + HYDROGEN

    Hope this helps :smile:
