Q

What is the relationship btw pH and H+ concentration?

A

inverse relationship

lower pH = more acidic / more H+
high pH = more basic / less H+ & more OH

Q

What are binary acids and how are they named?

A

binary acids - acids made wt monoatomic anion

add enough H+ ions so it is a neutral compound
in formula ALWAYS PUT H FIRST

hydro (shortened ion name) ic acid

Q

What are foxy acids and how are they named?

A

oxygen acids - acids made wt polyatomic anions

add enough H+ until neutral compound
ALWAYS WRITE H FIRST IN FORMULA

no ‘hydro’ instead:

  • ic acid (polyatomic anions ending with -ate)
  • ous acid (polyatomic anions ending with -ite)

Q

What needs to be included in a dissolution equation?

A

dissolution equation = complete ionic equation

therefore must have:

  1. (aq) solutions split into ions SHOW CHARGES!!
  2. (s) (l) (g) stay bonded
  3. balanceed

Q

What is a net ionic equation?

A

only shows species that participate in chemical reaction

NO SPECTATOR IONS

17
Q

What is a double displacement reaction?

A

chemical reaction in which 2 reactants swap anions

18
Q

What are precipitate reactions?

A

type of double displacement reaction

chemical reaction that produces precipitate from mixing 2 aqueous solutions
