Q

What determines the strength of an acid or base?

A

strong acids and bases have many ions in solution, acids are relative to number of H3O+ ions and bases are relative to OH- ions

17
Q

Are acids proton donors or acceptors?

A

donors

18
Q

Are bases proton donors or acceptors?

A

acceptors

19
Q

what species determines pH

A

Hydrogen ions

20
Q

What is constitutes a buffer?

A

A weak acid or weak base and its conjugate base or acid.

21
Q

What does an ionization equation look like?

A

NH3 + H2O NH4+ + OH- (starts with a compound and water as reactants, end with ions as products)

22
Q

What does a hydrolysis equation look like?

A

(“hydro” “lysis” breaking water)

NH4+ + H2O NH3 + H3O+
S2- + H2O HS- + OH-

(starts with ion and water, breaks the water up into acid or base along with OH- or H3O+)

23
Q

What does a neutralization equation look like?

A

always ends with H2O as a product

HCN + KOH –> KCN + H2O

H3O+ + OH- –> 2 H2O

24
Q

What does a dissociation equation look like?

A

compound breaks down into ions

KOH –> K+ + OH-

KBr –> K+ + Br-

25
Q

When a salt is dissociated to join its acid or base counterpart what does that look like?

A

NaCl => NaOH + HCl

AlCl3 => Al(OH)3 + HCl

26
Q

What is produced if a strong acid and strong base combine?

A

neutral

27
Q

What is produced if a weak acid and weak base combine?

A

neutral

28
Q

What is produced if a weak acid and strong base combine?

A

base

29
Q

What is produced if a strong acid and weak base combine?

A

acid
