Criss Cross Method - How it Works

Criss Cross Method - How it WorksWhen it comes to chemistry, most of us are familiar with the Criss Cross Method. What we don't know, however, is the strength and flexibility of this method. While the Criss Cross Method doesn't refer to anything in particular, it can be attributed to an informal experiment performed by Dr. E. R. Criss. From that point, the method has been implemented and adopted by a lot of research laboratories all over the world.Many students nowadays might not be aware of the method but those who are should be acquainted with it before moving ahead. Students can utilize the Criss Cross Method by basing their experiments on different chemicals and substances that exist today.As mentioned earlier, Criss uses four general terms in describing the relationships between these chemicals and substances. The first term is the single point of contact. The second is the compound. The third term is the double point of concentration and the last is the triple point of concentr ation.In the single point of contact, there is one chemical that is always present. For example, ammonia, ammonia gas, glycerol, glycerin, etc. A similar term is the 'Equilibrium Point'. This term is different from the equilibrium of temperature and pressure, which describes the ideal case of the system.There are many other terms that can describe the same chemical property. These can include the rheological property of viscosity and also the thermal conductivity of the substance. All of these are terms that describe the chemical properties that determine the location of the two chemicals.The compound is exactly what it sounds like. In Criss Cross, these are substances that have the capacity to undergo changes in molecular size, such as water and ammonia. The compounds are actually particles that have a very small amount of volume and they can be found in food items or in the atmosphere. They have specific mass, which means that they possess specific gravitational pull.The third ter m is the double point. This refers to the point at which the concentrations of two substances reach a maximum point. The second point is the triple point where both substances have reached an equilibrium value.The Criss Cross Method can be used to study compounds such as glucose, ethanol, carbon dioxide, glucose polymer, etc. Although these substances have a similar chemical formula, they are usually not solids. They tend to form as mixtures and liquids due to their presence in biological systems.
