Intro to Titration

A titration is a technique used to

• measure the volume of a solution.

• work out the concentration of a solution.

• determine the pH of an unknown solution.

• determine the mass of solute in a solution.

A standard solution is one whose

• pH is known.

• salinity is known.

• concentration is known.

• mass is known.

What is the purpose of the indicator in a titration?

• To show the end of the reaction.

• To determine the acidity.

• To determine alkalinity.

• To determine the concentration of a solution.

What apparatus is required for a titration?

i. Pipette

ii. burette

iii. conical flask

iv. measuring cylinder

• i and ii only

• i, ii and iii only

• ii only

• i and iv only

The pipette is used to

• measure volume of solution

• hold the solution

• accurately measure volume of solution

• measure the mass of solution.

The burette is used to

• accurately measure the volume of solution.

• Add solution to another solution

• hold the solution

• accurately measure the volume of solution and add to the other solution.

What is the best indicator to use in an acid base titration?

i. Universal indicator

ii. Litmus

iii. Phenolphthalein

iv. methyl orange

• i, ii, iii and iv

• ii, iii and iv only

• i and ii only

• iii and iv only

The titration should be repeated until

• you run out of solution

• titre readings are consistent

• you are tired

• the pH is consistent
