LT#2: Acids, Bases and Writing Ionization Equations Flashcards
What are the steps to name a Binary Acid?
Step 1: prefix “hydro”
Step 2: root name of non-metal
Step 3: suffix “ic acid”
What are the rules to name a Oxyacid?
IF the poly ends in “ate” change it to “ic acid”
IF the poly ends in “ite” change it to “ous acid”
DO NOT ADD hydro to beginning oxyacids
How do you name Bases?
No changes (same rules as ionic compounds)
What are the steps/rules for writing ionization equations?
- Water breaks apart compound into ions.
- For acids, only one H+ falls off
- For bases, all OH– fall off. Need to balance equation after.
- All states must remain aq
