What Is “ppm”? The ppm is an acronym for “parts per million”, a unit of measure that describes how much of one substance (called the “solute”) is dissolved in a sample of water (called the “solvent”). This is a measurement of concentration (or density), which can often be helpful in our daily lives. The ppm…
HYDROGEN GAS IN THE WATER The manner in which hydrogen gas is dissolved in the water has an effect on its stability and rate of exsolution (coming out of solution) and dissipation. Hydrogen gas can exist in water as fully dissolved gaseous solutes, colloidal and suspension forms, as well as large macrobubbles that exit almost…
INTRODUCTION The concentration of hydrogen gas (H2) is often reported in molarity (moles/liter (M) or milimoles/L mM), parts per million (ppm), parts per billion (ppb) or miligrams per liter (mg/L). In dilute concentrations, 1 ppm is about the same as 1 mg/L and they are often used interchangeably. The molar mass of molecular hydrogen is…
WATER IMPORTANCE Water is the universal solvent;1 it can exist as a solid, liquid or gas.2 It is necessary for the functions of life3 and for life to function.4 Water is the life-giving fluid that is always at the heart of creation.5 Its presence supports life, and its absence brings death.6 Water in liquid state is the principle criteria for…
HISTORY One of the important parameters of water quality is the pH.1 A pH measurement reveals whether the solution is acidic, neutral, or alkaline. The chemistry of water has been discussed previously, which will help us understand what pH really is. In the most basic sense, pH refers to the negative logarithmic (log) measurement of the H+ion concentration in…
