Understanding the Formula for MEQ: A Comprehensive Guide

The formula for MEQ, or milliequivalents, is essential in various fields, including chemistry and medicine. Knowing how to calculate MEQ can aid in effective drug dosing, nutrient analysis, and more. In this guide, we’ll unpack the formula and illustrate its significance.

The Fundamentals of MEQ Calculation

MEQ represents the chemical activity of an electrolyte in a solution. The formula is calculated based on the amount of substance and its valency. The basic formula is:

MEQ = (mg of substance / molecular weight) × valency

Understanding each component helps in accurately determining the MEQ for various compounds.

What Does Valency Mean in the MEQ Formula?

Valency refers to the combining capacity of an element. In the context of MEQ, it signifies how many charges an ion carries. For example, sodium (Na+) has a valency of 1, while calcium (Ca2+) has a valency of 2.
