Question

When you need accurate measurements of chemicals, you should use ______ because ______

A) only glassware that has been calibrated because some volume markings are only estimates
B)hold solutions measured by other glassware or to do smaller qualitative tests
C)carefully deliver volumes of liquid and notably has a stopcock at the bottom to dispense
D)Measuring out a volume of liquid; reasonable accuracy

Answer 1

Use a burette for precise chemical measurements, such as in titrations, due to its accuracy and the control it provides. A graduated cylinder is suitable for less precise volume measurements of a chemical solution.

Step-by-step explanation:

When you need accurate measurements of chemicals, you should use a burette because it is designed to carefully deliver volumes of liquid and notably has a stopcock at the bottom to dispense the exact amount needed for reactions like titrations.

For measuring a volume of water in a chemical solution where high precision is not necessary, a graduated cylinder would be suitable, as it allows you to measure varying amounts of liquids with reasonable accuracy.

Different glassware like pipettes and volumetric flasks also provide precise measurements depending on the required volume and accuracy.

When you need accurate measurements of chemicals, you should use a burette because it is calibrated and provides precise volume measurements.

Glassware such as beakers or flasks may have volume markings that are only estimates, so they are not suitable for accurate measurements.

A burette has a stopcock at the bottom that allows you to carefully deliver volumes of liquid. It is commonly used in titrations, where precise volume measurements are crucial.
