Question

a weak acid is 5% ionized at equilibrium. Therefore, we can say that the ionization reaction is ____ favored because ___
a. product; the amount of products << the amount of reactants

b. reactant; the amount of products << the amount of reactants

c. reatant; >> the amount of products >> the amount of reactants

d. product; the amount of products >>the amounts of reactants

e. neither; not enough info givem

2. for the follwoing reaction of formic acid with water

HCOOH + H2O <-----> H3O+ HCOO-

which of the following statements is correct?

a. HCOOH and H20 are a conjugate/acid base pair

b. H2O and HCOO are a conjugate acid/base pair

c. HCOOH and H3O are a conjugate acid/base pair

d. HCOOH and HCOO are a conjugate acid/base pair

3. if we gradually increase the concentration of a strong base in water without changing the volume signifacntly, then the: '

a. hydroniun ions concentration will decrease while the hydroixed ion concentration will increase

b. hydronium ion concentratin will increase while the hydroxide ion concentration will decrease

c. conentratons of hydronium an hydroxide will both increase

d. concetration of hydronium and hydroixe ion will both decrease

e. concentrations of hydronium and hydroxide ions will be unaffected

Explanation / Answer

reactant; the amount of products << the amount of reactants

HCOOH and HCOO are a conjugate acid/base pair

hydroniun ions concentration will decrease while the hydroixed ion concentration will increase
