Answer 2

Arrhenius base

Question 3

When H^+ dissociates from an acid in water, what does it form

Answer 3

Hydronium, H3O^+

Question 4

This substance accepts a proton and must have a lone pair

Answer 4

Bronsted-Lowry base

Question 5

This substance contains H and donates a proton (H^+)

Answer 5

Bronsted-Lowry acid

Question 6

Are all Bronsted-Lowry acids also Arrhenius acids?

Answer 6

Yes

Question 7

What is neutralization?

Answer 7

When an acid and base react, and the H^+ from the acid combines with the OH^- from the base to form H2O

Question 8

What are the seven strong acids?

Answer 8

HBr - hydrobromic
HCl - hydrochloric
HI - hydroiodic
HClO4 - perchloric
HNO3 - nitric
H2SO4 - sulfuric
HClO3 - chloric

Question 9

Is HF a strong acid, weak acid, strong base, or weak base?

Answer 9

Weak acid

Question 10

Is H2S a strong acid, weak acid, strong base, or weak base?

Answer 10

Weak acid

Question 11

Is HCN a strong acid, weak acid, strong base, or weak base?

Answer 11

Weak acid

Question 12

Is HClO a strong acid, weak acid, strong base, or weak base?

Answer 12

Weak acid

Question 13

Is HNO2 a strong acid, weak acid, strong base, or weak base?

Answer 13

Weak acid

Question 14

Is CH3COOH a strong acid, weak acid, strong base, or weak base?

Answer 14

Weak acid

Question 15

What are 8 common strong bases?

Answer 15

Ba(OH)2, Ca(OH)2, CsOH, LiOH, KOH, RbOH, NaOH. Sr(OH)2

Question 16

Is NH3 a strong acid, weak acid, strong base, or weak base?

Answer 16

Weak base (Bronsted-Lowry)

Question 17

Is F^- a strong acid, weak acid, strong base, or weak base?

Answer 17

Weak base (Bronsted-Lowry)

Question 18

For HA(aq) + H2O(l) ⇌ H3O^+ (aq) + A^- (aq), where HA is a generic acid, what is the acid dissociation constant Ka?

Answer 18

Ka = [H3O^+][A^-]/[HA]

Question 19

For a strong acid, is the acid dissociation constant Ka large or small?

Answer 19

Large because strong acids dissociate completely in water

Question 20

For a weak acid, is the acid dissociation constant Ka large or small?

Answer 20

Small because weak acids dissociate little in water

Question 21

Are oxoacids where the number of O atoms does not exceed the number of the number of ionizable protons by at least 2 strong or weak acids?

Answer 21

Weak (ex: HClO, HNO2)

Question 22

Are carboxylic acids (RCOOH) strong or weak acids?

Answer 22

Weak

Question 23

Is a molecule containing N bonded to three things a strong/weak acid or a strong/weak base?

Answer 23

Weak base (ex: NH3, RNH2, R3N, R2NH)
