The aqueous solution in the classical reaction contains glucose, sodium hydroxide and methylene blue. [14] In the first step an acyloin of glucose is formed. The next step is a redox reaction of the acyloin with methylene blue in which the glucose is oxidized to diketone in alkaline solution [6] and methylene blue is reduced to colorless leucomethylene blue.

Chemistry education is important because the field of chemistry is fundamental to our world. The universe is subject to the laws of chemistry, while human beings depend on the orderly progress of chemical reactions within their bodies. [2] Described as the central science, chemistry connects physical sciences with the life sciences and applied ...
8 states require students to take a state-mandated government/civics test. 9 states require a social studies test as a requirement for high school graduation. The lack of state-mandated student accountability relating to civics may be a result of a shift in emphasis towards reading and mathematics in response to the 2001 No Child Left Behind ...
The following outline is provided as a topical overview of science; the discipline of science is defined as both the systematic effort of acquiring knowledge through observation, experimentation and reasoning, and the body of knowledge thus acquired, the word "science" derives from the Latin word scientia meaning knowledge.
At the same time, teachers need to develop a sound understanding of issues from various disciplines—philosophy, history, geography, social studies, politics, economics, environment and science. This is so that students’ knowledge base can be appropriately scaffolded to enable them to effectively engage in discussions, debates and decision ...
