Environmental Enlightenment #119

By Ami Adini - Reissued December 15, 2015


This is a SHORT, LIGHT and SIMPLE newsletter. Its purpose is to rekindle in the initiated terminology they have once learned, and enlighten the uninitiated on terms they may have heard but never known the meaning of.

Interesting Numbers

A solution is made of a solvent and a solute.

When sugar dissolves in water, sugar is the solute and water is the solvent.

The quality of being able to dissolve into another medium is solubility.

Different substances are soluble inside a given medium in different degrees.

Sugar and salt are both soluble in water, but sugar is more soluble than salt.

At room temperature, you can dissolve 15 pounds of sugar in one gallon of water; but only 3 pounds of table salt.

animated example
Benzene is a carcinogen. It has been discharged to groundwater from past generations of leaking underground gasoline tank installations.
Compared to salt and sugar, benzene’s solubility is miserably low; at room temperature you cannot get more than one hundredth (0.01) of a pound of it in a gallon of water. But, when you consider that the maximum level allowed in drinking water is one pound for every 120 million gallons of water, you can see that benzene is soluble enough to render vast amounts of groundwater undrinkable.
For example, one tea spoon of benzene completely solubilized will render 280,000 gallons of water undrinkable. At 8 cups a day, it will take you 1,500 years to drink that much water.
