Question

select the most appropriate tool for each measurement.
exactly 200.00 ml salt solution: volumetric flask
a 0.02 - ml acid solution: 1 - ml pipette
approximately 400 ml water: volumetric flask beaker

Explanation:

• A volumetric flask is used for measuring an exact volume of liquid. So, for exactly 200.00 mL salt solution, the volumetric flask is appropriate.
• A 1 - mL pipette can be used to measure a very small volume like 0.02 - mL acid solution (as it can measure volumes within its capacity accurately).
• A beaker is used for measuring an approximate volume. So, for approximately 400 mL water, a beaker is the right choice.

Answer:

Exactly 200.00 mL salt solution: volumetric flask
A 0.02 - mL acid solution: 1 - mL pipette
Approximately 400 mL water: beaker
