Understanding Conductivity Curves in Titrations

What unit is used to measure the conductivity of a solution?

• Milliliters per square meter

• Millisiemens per square meter per mole

• Millisiemens per liter

• Millimeters per mole

Which factor does NOT affect the conductivity of a solution?

• Ion concentration

• Ion mobility

• Color of the solution

• Temperature

How can the equivalence point in a titration be determined using conductivity?

• By observing a color change

• By measuring the temperature change

• By measuring the pH

• By plotting conductivity against the volume of reactant added

What happens to the conductivity at the equivalence point in a titration involving HCl and NaOH?

• It reaches a specific value due to the presence of spectator ions

• It drops to zero

• It remains constant

• It becomes infinite

In a strong acid-strong base titration, what shape does the conductivity curve typically have?

• A zigzag pattern

• A U-shape

• A V-shape

• A straight line

What is the initial conductivity like in a weak acid-strong base titration?

• Zero

• Very high

• Low

• Moderate

In a strong acid-weak base titration, what happens to the conductivity after the equivalence point?

• It decreases sharply

• It increases sharply

• It remains nearly constant

• It fluctuates randomly

Why is a weak acid-weak base titration more feasible with conductivity monitoring than with pH monitoring?

• Because pH changes are too rapid

• Because conductivity changes are more distinct

• Because pH changes are too gradual

• Because conductivity changes are more gradual

What is the significance of the conductivity curve in titrations?

• It helps determine the color of the solution

• It helps identify the type of acid used

• It helps measure the temperature change

• It helps determine the equivalence point

Which combination of acid and base results in a conductivity curve with two stages of increase?

• Weak acid and weak base

• Strong acid and strong base

• Weak acid and strong base

• Strong acid and weak base
