In this video we'll write the correct formula for Nitrous acid.
To write the formula for Nitrous acid we’ll use the Periodic Table, a Common Ion Table, and follow some simple rules.
Because Nitrous acid has a polyatomic ion (the group of non-metals after the metal) we’ll need to use a table of names for common polyatomic ions, in addition to the Periodic Table.

--- General Rules ----
If the name for the acid is:
Hydro + stem + ic
1. Write H.
2. Use the stem to find element name on the
periodic table.
3. Balance the charges.
Stem + ic
1. Write the ion: stem + ate
2. Look up ion on Common Ion Table.
3. Write H and then the ion formula.
4. Balance the charges.
Stem + ous
1. Write the ion: stem + ite
2. Look up ion on Common Ion Table.
3. Write H and then the ion formula.
4. Balance the charges.
