Question

1/ The purpose of a titration experiment is to:

Select one:

a. measure the amount of heat absorbed or released by a reaction.

b. calculate the rate at which a reaction occurs.

c. find the optimal color for a set of reactants.

d. determine the amount of a specific compound in a solution.

What is the purpose of an indicator (like phenolphthalein) in a titration?

Select one:

a. Change color when the reaction is safe.

b. Produce a color that is pleasing to the eye.

c. Visually show when the endpoint has been reached.

What is the balanced equation for Practice Problem 4.14 B on pae 164 of the text?

Select one:

a. 2 HCl (aq) + Ba(OH)2 (aq) --> 2 H2O (aql) + BaCl2 (s)

b. 2 HCl (aq) + Ba(OH)2 (aq) --> 2 H2O (l) + BaCl2 (aq)

c. HCl (aq) + 2 Ba(OH)2 (aq) --> H2O (l) + 2 BaCl2 (aq)

d. HCl (aq) + Ba(OH)2 (aq) --> H2O (l) + BaCl (aq)

e. HCl + Ba(OH)2 --> H2O + BaCl
