Titration 101

Look at the image above. This is the reaction of:

• A strong base being added to a strong acid

• A weak base being added to a strong acid

• A strong base being added to a weak acid

• A strong acid being added to a weak base

Assuming the initial reagent in the flask is a strong monoprotic acid, estimate its concentration.

• 0.1 mol/dm3

• 0.01 mol/dm3

• 0.2 mol/dm3

• 0.02 mol/dm3

Which of the following statements about this titration is accurate?

• Strong acid was added to weak base

• Strong base was added to weak acid

• Weak acid was added to strong base.

• Strong base was added to strong acid.

Calculate the initial concentration of 25ml of the reagent H-X where the substance added had a concentration of 0.1 mol/dm3.

• 0.06 mol/dm3

• 0.6 mol/dm3

• 0.16 mol/dm3

• 0.02 mol/dm3

Determine the pKa of the reactant.

• 8.8

• 15.0
