Lesson 2: Ionic equations Flashcards
1
Q
What do ionic equations show?
A
- Ionic equations show the ions involved in a reaction.
They only show particles that have changed
2
Q
What are “spectator ions”?
A
- Spectator ions are on both sides of an equation.
They haven’t changed
3
Q
What are the steps to writing an ionic equation?
A
1.) Balance the equation
2.) Split ionic compounds into ions.
3.) Cancel out spectator ions
4.) Write net equation
4
Q
When are ionic compounds formed ?
A
When non - metals react with metals.
5
Q
What are polyatomic ions?
A
- Ions that consist of more than 1 type of atom.
6
Q
What are monoatomic ions?
A
- Ions that consist of one type of atom.
7
Q
How do particles change in chemical reactions?
A
- Particles change by gaining/ losing electrons.
8
Q
What is the ionic formula for “hydroxide?”
A
OH⁻

11
Q
What is the ionic formula for “sulphate”?
A
SO₄²⁻
12
Q
What is the ionic formula for “carbonate”?
A
CO₃²⁻
13
Q
What is the ionic formula for “phosphate”?
A
PO₄³⁻
14
Q
What 2 things make an ionic equation balanced?
A
- Same overall charge
- Number of atoms on each side
15
Q
How is the “net ionic equation” achieved?
A
- You must cancel out spectator ions.
