Definition

The process of measuring the pressure that is created when a solvent moves through a semipermeable membrane due to differences in concentration of solutes.

Example

Osmometry is used in laboratories to determine the osmotic pressure of various solutions.

Conversation

Have you ever heard of osmometry?

I think so, but I’m not really sure what it is.

It's the measurement of osmotic pressure, actually.

That sounds interesting! I should look it up.

Root Explanation

Osmometry → It is formed from "osmo-" (from Greek "osmos", meaning push or thrust) and "-metry" (from Greek "metron", meaning measure). The word refers to the measurement of osmotic pressure, which is the pressure required to stop the flow of a solvent through a semipermeable membrane due to osmosis.

Memory Tip

Think of 'osmosis' as a process that involves a 'push' or 'thrust' ('osmo-') and 'measure' ('-metry') to remember that osmometry is about measuring that process.
