Chapter 8 Flashcards
What would you see if a precipitation reaction were to take place in a beaker
Fog
Color change
Turn cloudy
What are the strong acids that you need to know
Acid: HCl, H2SO4, H3PO4, HNO3
What are the bases that you need to know
NaOH, KOH, LiOH, Ca(OH)2, Ba(OH)2
Why do spectator ions not included in the net ionic equations
They don’t do anything in the reaction
What is an acid-base reaction
It forms a liquid (water)
Neutralization
Give 4 examples of “driving forces” that make reactants to form products
Forming a solid- precipitate
Forming a gas
Forming a liquid
Transfer of electrons
What is a precipitation reaction
Occurs when cations and anions of aqueous solutions combine to form an insoluble ionic solid called a precipitate
Ionic compound
Compound formed between a cation and an anion
- usually metal and non metal
Soluble ionic salt ?
Can dissolve in water and is aqueous
NaCl
Insoluble ionic salt ?
Can not dissolve in water and is a solid
How can you determine if there’s a reaction
By using the solubility rules
What does it mean to be water-soluble?
Ionic compound can be “pulled apart” by the water molecule
…. Ionic compounds can dissociate separate into ions of they are soluble
How do we know ionic compounds dissociate into ions ?
The aqueous solution becomes an electrolyte and co ducts electricity
In a reaction the cations do what
Trade places
Types of double displacement reactions
- Precipitation- solid forms
2. Acid/base (neutralization) liquid water forms
