LT#2: Acids, Bases and Writing Ionization Equations

Question 1

What are the steps to name a Binary Acid?

Answer 1

Step 1: prefix “hydro”

Step 2: root name of non-metal

Step 3: suffix “ic acid”

Question 2

What are the rules to name a Oxyacid?

Answer 2

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

Question 3

How do you name Bases?

Answer 3

No changes (same rules as ionic compounds)

Question 4

What are the steps/rules for writing ionization equations?

Answer 4

• 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
