Glossary, basic terms to understand

Reagent – Any substance used in chemical reactions, analysis or research.
Solute – The substance which dissolves in a solution.
Solvent – The substance which dissolves another to form a solution. For example, in a sugar and water solution, water is the solvent; sugar is the solute.
Solution – A mixture of two or more pure substances. In a solution one pure substance is dissolved in another pure substance uniformly. For example, in a sugar and water solution, the solution has the same concentration throughout, ie. it is uniform.
Concentration – The ratio of solute to solution e.g. 10mg per mL, 10mg/mL, 10mg/cc.
Suspension – Typically a solution is transparent because solute particles are microscopic. A suspension has visible particles.

Introduction to Chemical Solutions

Chemical solutions involve dissolving a reagent in liquid to make it easier to measure, without relying on an expensive or imprecise scale. Assuming the solution is at a uniform concentration, measurement of the reagent can be done precisely using volumetric measurement tools like a beaker or pipette.

Selecting an adequate solvent

If you do not select an adequate solvent your solute will precipitate out of solution or lack uniformity, making handling difficult.

We post solvents with relatively high solubility on our product listings, under the specification on the row titled Solubility:

However we have only verified solubility up to the concentrations used in our own solution products. If you need more precise data we recommend conducting your own solubility experiments at given concentrations with different solvents.

Selecting your concentration

Solutions are easier to make and handle at lower concentrations. If you saturate a solution the solute may precipitate out of solution thus ruining the uniformity. Changing the pH or temperature of your solution can also result in precipitation.

Solution Example: Using mass by volume (m/v)

Formula
The formula for mass by volume (m/v) is:
