Acid/Base

Question 1

Acid

Answer 1

Has H in its formula
Dissociates in water to give H ions
Proton donor

Question 2

Base

Answer 2

Has OH in formula
Dissociates to give OH in water
Proton acceptor

Question 3

Strong Acid

Answer 3

High dissociation (100%)
High Ka

Question 4

Answer 4

Very little dissociation

Low Ka

Question 5

List of Strong Acids

Question 6

List of Strong Bases

Answer 6

NaOH, KOH, Ba(OH)2, Ca(OH)2, NaO, KO

Question 7

List of Weak Acids

Answer 7

fornic acid (HCOOH), acetic acid (CH3COOH), benzoic acid, phenol, HF, HCN, HNO2 (nitrous acid), H2SO3 (sufurous acid), HOBr, HOCl, HOCl2

Question 8

List of Weak Bases

Answer 8

ammonia (NH3) and its derivatives (hydrogens replaced by a group - CH3NH2 [methyl amine], C2H5NH2 [ethyl amine], (CH3)2NH [dimethyl amine], (CH3)3N [ trimethyl amine], aniline, pyridine)

Question 9

Conjugate base of Weak Acid

Answer 9

Weak base

Question 10

Conjugate acid of Weak Base

Answer 10

Weak acid

Question 11

Conjugate of Strong Acids/Bases

Answer 11

Neutral

Question 12

Acid Strength Increases

Answer 12

High Ka
Low pKa
Concentration of H will be higher, concentration of OH will be lower, pH will be lower, pOH will be higher

Question 13

Base Strength Increases

Answer 13

Higher Kb
Lower pKb
Concentration of OH will be higher, concentration of H will be lower
pOH be lower
pH will be higher`

Question 14

What affects acid strength?

Answer 14

Ease H ions can be removed, factors:
Electronegativity
Bond Strength

Question 15

Electronegativity

Answer 15

Tendency of an atom in a bond to attract shared electrons to itself, this means that the more electronegative an atom is, the easier it is to remove H, stronger the acid

Question 16

Bond Strength

Answer 16

Stronger the bond, the harder to break and remove H, weaker the acid
