What is Viscosity in Chemistry?

Viscosity is the tendency of fluids, in either liquid or gas form, to resist forces that act against them. For example, if you tried to rapidly stir pure water while rapidly stirring molasses, you would find it much more difficult to stir the latter. With this in mind, viscosity can also refer to how thick a fluid is. Viscosity can...

What is the Definition of Evaporation in Chemistry?

Evaporation is a natural or synthesised process by which liquid substances transition into a gaseous state with the action of heat.  The water cycle, which involves the evaporation and precipitation of water, is one of the major driving forces of the weather and global climate, and one of the best examples of evaporation. Evaporation is generally a cooling process that has...

What is Titration Used For in Real Life?

Titration is an analytical quantitative method of determining the concentration of a known analyte by allowing it to gradually react with a titrant until an endpoint is reached. It has several industrial, medical, and commercial applications. Most students who have taken chemistry subjects in high school are familiar with the basic methods of titration. No matter what type of titration...

What is Methyl Red?

Methyl red is an azo dye, or a synthetic dye, which is one of the common chemical indicators used in the laboratory to determine pH transitions within a specific range. It’s most effective between pH 4.4 and pH 6.2.  If the pH level is below 4.4, its colour is red, and if it’s above 6.2, the colour turns yellow. If...
