## equation

[e-kwa´zhun]
an expression of equality between two parts.
Henderson-Hasselbalch equation a formula for calculating the pH of a buffer solution such as blood plasma, pH = pKa + log [BA/HA]; [HA] is the concentration of a free weak acid; [BA] the concentration of the ionized form of this acid; pKa the acid dissociation constant, a measure of the ionization equilibrium of the acid.

Q. how do i determine what is the right weight i need to be? i know there is a way to calculate it, an equation , what are the parameters in it ?

A. I don't mean to burst any bubbles, but BMI is definitely not a good way to determine what weight you should be. If you considered that a body builder or a professional athlete is considered obese under BMI standards then you would know what I mean. Here is an article about it I found on Medical News Today: http://www.medicalnewstoday.com/articles/49991.php
