In chemistry, a condenser is laboratory apparatus used to condense vapors – that is, turn them into liquids – by cooling them down. [ 1 ] Condensers are routinely used in laboratory operations such as distillation , reflux , and extraction .
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.
Below is a table of amino acids produced and identified in the "classic" 1952 experiment, as analyzed by Miller in 1952 [3] and more recently by Bada and collaborators with modern mass spectrometry, [7] the 2008 re-analysis of vials from the volcanic spark discharge experiment, [7] [55] and the 2010 re-analysis of vials from the H 2 S-rich ...
In chemistry, fractional crystallization is a stage-wise separation technique that relies on the liquid-solid phase change. fractional crystallisation. This is an old established method which is nevertheless capable of excellent results and a description is available in "The practical Methods of organic Chemistry" by Ludwig Gattermann in 1898 and a translation was available in English by ...
These experiments enable one to artificially "enter" the reaction at any point, as the initial concentrations of one experiment (the intercepting reaction) are chosen to map directly onto the anticipated concentrations at some intermediate time, t, in another (the parent reaction). One would expect the reaction progress, described by the rate ...

Wet chemistry is a form of analytical chemistry that uses classical methods such as observation to analyze materials. The term wet chemistry is used as most analytical work is done in the liquid phase. [1] Wet chemistry is also known as bench chemistry, since many tests are performed at lab benches. [2]
