The various types of chemicals necessary for conducting laboratory work

The Chemistry lab is a well-known place for finding a massive array of different kinds of chemicals arranged in labeled bottles across shelves. Based on reactivity the chemicals can be divided into two generalized categories which include:

  • Mild chemicals: These chemicals do not cause grave injury upon physical contact. And it might result in some amount of irritation if it gets poured over the skin in vast quantity. Salts and bases usually come under the category of less reactive.
  • Reactive chemicals: These are dangerous chemicals that will burn or scald the epidermal layer upon contact and can also scar the region for an extended period. Acids and corrosive reagents are considered highly reactive.

However, as far as lab chemicals are concerned, there are multiple categories which have several items under each group. A few of these chemical categories are discussed below:

  • Solvents: These chemicals are for dissolving solid compounds or elements or mixtures. Depending upon the particular type of solute the solvent has to be chosen. Water is genially known as the universal solvent, and in most cases of inorganic analysis of salts, the solubility of the salt compound in water gets tested for observation. Chemical solvents are also present that can dissolve compounds which are insoluble in water.
  • Salts: Different kinds of chemical compounds exist in salt form. To hone the skills of students, mixtures of different salts are often given for inorganic analysis. Different types of salts like barium sulfate, ferric sulfates, etc. are available in packaged boxes for purchase.
  • Caustic agents: Chemicals that have a pH value above seven are considered to be a base or alkali. These are important for doing several experiments in the laboratory. Caustic solutions are often observed in laboratories and include common bases like sodium hydroxide.
  • Acids: Acids have pH below 7 and are present in laboratories in both concentrated and diluted form. The concentrated acids are incredibly corrosive, and one needs to handle that with utmost care.
  • Oxides of metals: Metallic oxides are often needed for specific experimental processes and are available in a well-stocked laboratory.

The need for procuring premium chemicals

For stocking any laboratory, the chemical materials should be of a reliable quality which will enable an experimenter to acquire accurate results. Some chemical dealers also provide preparation materials and other peripheral equipment which include carriers of active ingredient, additives, aids for filtration, reaction auxiliaries, etc. 

As chemicals are variously used for purification purposes as well as for, enrichment of specific compounds or for the separation of matter into solid, liquid or gaseous states good quality chemicals are vital. You can buy chemicals in trial pack sizes or a considerable amount. But in case of a new dealer it is important to see the chemicals provided by the dealer in smaller quantity and if the quality is ensured then large orders for stocking the laboratory can be placed.

Hence while choosing any chemical dealer the quality of the provided chemicals and the range of their services ought to be evaluated.
