Volumetric Analysis Quiz

What is the primary purpose of a titration in volumetric analysis?

• To measure the temperature of a solution

• To determine the concentration of a solution

• To change the colour of a solution

• To measure the pH of a solution

Which piece of equipment is commonly used to deliver a precise volume of liquid during a titration?

• Beaker

• Pipette

• Burette

• Measuring cylinder

When preparing a standard solution, why is it important to use a volumetric flask?

• It is cheaper than other glassware

• It allows for precise measurement of volume

• It is easier to clean

• It can hold more solution than a beaker

How is the endpoint of a titration typically determined?

• By measuring the temperature change

• By observing a colour change

• By using a stopwatch

• By measuring the volume of gas produced

What is the molarity of a solution if 0.5 moles of solute are dissolved in 2 litres of solution?

• 0.25 M

• 0.5 M

• 1.0 M

• 2.0 M

Which of the following is a correct step in preparing a standard solution?

• Adding the solute directly to the volumetric flask without weighing

• Dissolving the solute in a beaker before transferring to a volumetric flask

• Filling the volumetric flask to the brim with solvent

• Using a pipette to add the solute to the volumetric flask

In a titration, what is the role of the indicator?

• To neutralise the solution

• To provide a visual signal of the endpoint

• To increase the reaction rate

• To stabilise the pH of the solution

If 25.0 mL of a 0.1 M NaOH solution is required to neutralise 50.0 mL of HCl, what is the concentration of the HCl solution?

• 0.05 M

• 0.1 M

• 0.2 M

• 0.4 M

What is the first step in preparing a standard solution?

• Weighing the solute accurately

• Adding solvent to the volumetric flask

• Mixing the solution thoroughly

• Heating the solution

Which of the following is NOT a common error in titration?

• Misreading the burette

• Using an incorrect indicator

• Overfilling the volumetric flask

• Using a clean and dry pipette
