Green Solvent -Water


Water
A Green Solvent
 
Water is a unique chemical compound; it is made up of two hydrogen atoms, and one oxygen atom (H2O). Our bodies are composed mostly of water, so water is very important. But water is also important for its part as a solvent in environment behavior and industrial uses. In green chemistry, water has an important use as a green solvent. But, what are solvents anyway? Solvents are the fluid portion of a solution. Salts, acids, bases, and substances that contain hydrogen, oxygen, and nitrogen atoms use water as a solvent. When these substances combine with water solvent, they produce biological fluid like in urine. Substances found in the geosphere are brought there by the water solvent. Plant roots use the water solvent as a way of transport of its nutrients. Many industries use the water solvent in their jobs. The water solvent has many positive sides including being non-toxic, it being non-flammable, it is readily available for use, and it is not expensive. With positives sides there has to be a negative side. The negative side is water has a high boiling point, it is corrosive, and it expands when it freezes. Even though there is a negative aspect of water as a solvent, I believe the positives outweigh the bad. Green chemists should take advantage of water. The water solvent could change the way chemistry is done.
