PPM is calculated by dividing the mass of the solute by the mass of the solution, then multiplying by 1,000,000. Both parts of the equation must be in the same format, weight or volume. What is the value of 1 ppm? 1 PPM is equal to 0.0001 percent of the solution. It is equal ...
PPM Definition:PPM stands for parts per million. It is commonly used to express concentration and temperature coefficients. Read More Unraveling PPM: What It Really Means By Anne Marie Helmenstine, Ph.D. Also Known As:parts per million Examples:100 ppm is identical to 0.01%...

The "parts per" notation is used to describe dilute solutions in chemistry and engineering, but its meaning is ambiguous and it is not part of the SI system of measurement. The reason the system is ambiguous is because the concentration depends on the original unit fraction that is used. For...

In chemistry, the word is most often applied toa heterogeneous mixture. This is one which has a non-uniform composition. Amixtureof sand and water is heterogeneous. Concrete is heterogeneous. In contrast, a homogeneous mixture has a uniform composition. An example is a mixture of sugar dissolved...
In reality, there are no absolutely 100% pure chemical compounds, as there is always some minute contamination. Indeed, as detection limits in analytical chemistry decrease, the number of impurities detected tends to increase.Impurities are either naturally occurring or added during synthesis of a ...
