Who invented bichromate cell?
The bichromate cell was invented by Johann Wilhelm Hittorf in the mid-19th century. It is a type of electric cell that generates current from chemical reactions involving potassium bichromate.
What has the author Hamish Worgan written?
Hamish Worgan has written: 'Gum bichromate printing process'
What has the author G C Laws written?
G. C. Laws has written: 'Chromate versus bichromate' 'Metzograph blocks from ordinary negatives' 'Flashing'
What is the name of ionic compound Cr2O3?
That would be the bichromate or sometimes called the dichromate ion. Example: Sodium bichromate (or sodium dichromate) is Na2Cr2O7.
Can you use chromatography for colourless substances?
Yes, spectrophotometry can be used in the determination of the concentration of the colorless solutes. Different solutes will rise to a different degree.
Is chromium a metal?
Chromium is the hardest metal; Mohs hardness of chromium is 8,5.
What is the chemical name of BaCr2O7?
It's name is "barium dichromate". Some people also use the antiquated (and wrong) term "bichromate", which should no longer be used. (See also the provided link.)
What happens when pH of a solution of dichromate ions is raised?
Was just looking this up myself. pH decreases according to the data shown in this old report published by the American Chemistry Society. The dichromate ions in the presence of water, dissociate into bichromate, which then dissociate further to form chromate and H+ ions. Leading to decreasing pH (more acidic). Equilbrium constants can be calculated and are affected by increasing concentration of dichromate ions.
How many moles of 2-butanol are oxidised by 1 mole of dichromate?
1 mole of dichromate releases 3 moles of atomic oxygen during oxidation process so it may oxidize 3 moles of butanol.Added:The answer (three moles butanon) is correct, but not the explanation.This oxidation has nothing to do with 'oxygen atoms', instead CrVI (in bichromate) taking up 3 electrons to form CrIII cations.Secundairy alcohols, like 2-butanol, are only oxidised till a keton is formed (butanon), according to:3 (CH3)CHOH(C2H5) + Cr2O72- + 8 H+ --> 3 (CH3)CO(C2H5) + 2 Cr3+ + 7 H2OPlease note there is NO change in the number of 'oxygen atoms' in the 2-butanol changing to butanon.
Is HCl an oxidizing agent or reducing agent?
reducing agent because it has room to gain electrons so it will be oxidized by an oxidizing agent. It is in the reduced form and can reduce other molecules by accepting their electrons. Therefore, NADH is the reducing agent and NAD+ is the oxidizing agent
What does it mean if a chemical symbol in a chemical formula has no subscript?
There is one atom of that element in the molecule.
