Question

What piece of laboratory equipment is best-suited for accurately measuring the volume of a liquid?

Answer 1

Hint:In order to answer this question, to know the equipment which is best-suited for accurately measuring the volume of a liquid, we will first mention the name of the required equipment and then we will discuss more about the equipment.


Complete step-by-step solution:
Graduated cylinder is the laboratory equipment best-suited for accurately measuring the volume of a liquid.
A graduated cylinder, also known as a measuring cylinder or a mixing cylinder, is a piece of laboratory equipment that is used to determine the volume of a liquid. It has a cylindrical shape that is thin. The amount of liquid measured is represented by each marked line on the graduated cylinder.
When measuring the volume of a liquid, graduated cylinders are frequently used. Graduated cylinders are more exact and precise than laboratory flasks and beakers, but they should not be used for volumetric analysis. Instead, utilise volumetric glassware, such as a volumetric flask or volumetric pipette, which is even more accurate and precise.
To accurately read the volume, the observation must be made at eye level and read at the bottom of the liquid level's meniscus. The nature of the liquid in a closed, surrounded space is one of the key reasons why the volume is read via meniscus. By nature, molecular forces would attract the liquid in the cylinder to the wall around it. Depending on the type of liquid in the cylinder, this causes the liquid surface to form a convex or concave form. Reading the liquid at the bottom of a concave or convex liquid's meniscus is the same as reading the liquid at its meniscus. The liquid level will be read at the bottom of the concave meniscus, as seen in the image.
