Acid-Base Titration

What does the titration lab teach you?

• The importance of accuracy

• The importance of precision

• Important lab skills

• All of the above

What is the equivalence point for an acid-base neutralization?

• The amount of acid added = to base initially present

• The amount of base added = to acid initially present

• The amount of acid and base = to base initially present

• The amount of acid and base = to acid initially present

What specifically are you learning to calculate in this lab?

Acidic and basic solutions are generally

• equivliviant

• clear or colorless

• for titrations

• begin with the solutions separate

What is an acid base indicator?

• An instrument that measures how much base is present

• An instrument that measures how much acid is present

• A strip of paper that will indicate a color change

• A substance that changes color

When does phenolphthalein change color?

• When the pH measures on the probe

• When the pH reaches 8.0+

• When the pH is below 8.0

• When the pH reaches 5.0

How do you determine the volume of titrant delivered in a titration?

• Subtract the initial volume from the final volume

• Subtract the final volume from the initial volume

Are moles a measurable quantity?

• Yes

• No

• Depending on factors during an experiment

What is the formula to calculate molarity?

Why should you always refill the buret before each trial?

• To make sure you can comfortable read the buret

• To keep the buret lubricated through the trials

• To make sure you have enough titrant to complete each trial

• To keep more liquid in your buret while you titrate
