Unit 4 - Acid + Base, Redox, Molarity Flashcards

1
Q

Strong Acid and Strong Base

A

Both Base and Acid will ionize completely

So the H+ and OH- will be left to interact with each other

H+(aq) + OH-(aq) –> H2O (l)

Q

Weak Acid and Strong Base

A

The Acid will not ionize
The base will completely Ionize

OH- will pull some of the H+ off of the Acid

OH-(aq) + HAcid(aq) –> H2O(l) + Acid(Aq)

Q

Strong Acid and Weak Base

A

The Acid will completely ionize
The Base will not ionize
- only weak base is NH3

The H+ will ionize and it will add itself to the already made H2O molecules to make H3O

  • The base will come in and grab some of the H+ ions that are attached to the H3O –> making it H+ and H2O

B (aq) + H3O+ (aq) + Acid –> HB+ (aq) +H2O (l)

4
Q

Weak Acid and Weak Base

A

None will ionize
- exchange only between the two, simple displacement reaction

HA (aq) + B(aq) –> A (aq) + HB(aq)

Q

Metal Carbonate + Acid

A

Gas Forming Reaction
CO3,2-
carbonate + Acid –> metal salt + gas + water

CaCO3(S) + HA –> CA2 + H2CO3
- H2CO3 –> CO3 can react and it will release CO2

CaCO3(s) + HA –> CA2 + CO2 + H2O

Q

Metal Sulfide + Acid

A

Gas Forming Reaction
- displacement simple reaction
- will leave with a metal salt and a gas

Na2S (s) + 2HCl (aq) –> 2NACl (s) + H2S(g)

Q

Metal Sulfite + Acid

A

Gas Forming Reaction
Metal Sulfite + Acid –> metal salt + gas + water

Na2CO3(S) + HA –> CA2 + H2SO3
- H2SO3 –> SO2 can react and it will release SO2

  • Na2SO3 (s) + HCl(aq) –> NaCl + H2O (l) + SO2(g)

Q

Ammonium Salt + Strong Base

A

Metal Salt + NH3(gas) + H2O (l)

  • Ammounium salt is a strong acid
  • Base and Acid strong will make H2O
  • Left is a metal salt and the base NH3 which is weak

Q

Noble Gases Oxidation Number

A

0

17
Q

Oxygen Oxidation Number

A

2-

18
Q

In Peroxide Ions (O2,2−) Oxygen Charge

A

-1

19
Q

Halogen Oxidation Number?

Halogen Exception?

A

Usually -1

Halogen + Oxygen or Flourine
oxidation number of

Cl, Br, and I is not −1 –> matches the O or F oxidation number

20
Q

Hydrogen Oxidation Number

Nonmetals
vs Metas

A

Non metals = +1
Metals = -1

21
Q

Oxidation number of compounds

A

the sum of all of the element oxidation numbers

22
Q

Molarity is equal to what

A

solute moles/solution volume in Liters
