Answer 0

HCl HNO3 (Strongest Acid)
HBr H2SO4
HI
HClO3
HClO4

Question 1

Acid

Answer 1

Is a substance that produces H+ ions when dissolved in H2O.

Question 2

Weak Acids

Answer 2

HF
H2CO3
HC2H3O2
Don’t dissociate

Question 3

Base

Answer 3

Is a substance that produces OH- ions when dissolved in H2O.

Question 4

Strong bases

Answer 4

LiOH            FrOH          
NaOH          Ca(OH)2     
KOH            Sr(OH)2
CsOH          Ba(OH)2 
RbOH          Ra(OH)2

Question 5

Weak bases

Answer 5

Be(OH)2
Mg(OH )2
NH3
Don’t dissociate

Question 7

Dissociation

Answer 7

The initial compound/substance given is broken up by water into its separate ionic aqueous forms.

Na2SO4(s) ——-> 2Na+ (aq) + SO4^2- (aq)

Question 7

Salt

Answer 7

Substance that contains an anion from an acid & a cation from a base, H2O will always be the last product.

Question 7

Strong Vs. Weak Acids and bases

Answer 7

The strong dissociate unlike the weak ones.

Question 8

Precipitation Rxns

Answer 8

When most aqueous reactions form insoluble precipitates, or solids in the solution.

Question 10

Neutralization Rxns

Answer 10

Occurs when an acid reacts with a base to produce a salt & water.

Question 11

Gas Neutralization Rxns

Answer 11

Carbonates react with acids to form carbon dioxide gas. Reactions with first form carbonic acid. Will produce H2O and CO2

Question 12

Oxidation Numbers

Answer 12

Equals 0 unless it has a shown charge at the end, the it will equal to the amount of the charge.

Question 13

Reducing Agent & Oxidizing Agent

Answer 13

Reducing Agent: Loses electrons (+)

Oxidizing Agent: gains or stabilizes with electrons (-)
