What tool would you use to measure liquids in science?

Answer 1

It depends on what property of the liquid I wanted to measure.

If I wanted to measure volume, I'd first need to know how much of this liquid I was dealing with...it could be anything from a burette (if I just had a couple of milliliters of fluid) to a beaker if I was working with a "moderate" amount - the largest beaker Pyrex makes as a regular-stock item holds 2000 milliliters - to a huge tank with lines painted on the inside, if I was working with thousands of gallons of it.

Temperature? A thermometer, most of the time.

Specific gravity is measured with a hydrometer.

Viscosity is measured with a viscosimeter.

Occasionally you need to know the mass of the liquid so a balance or a scale is the tool to use.

If you need to measure the color of the product, a colorimeter is just the thing.

For testing alkalinity or acidity, there are a few tools you could use but if I had one handy (these are expensive so you may not) a digital pH meter is perfect for the job.
