Why potassium dichromate solution changes to green colour when it is added to ferrous ammonium sulphate solution?
The green color is due to the formation of chromium(III) ion, Cr3+, from the reduction of chromium(VI) ion, Cr2O72-. This reduction is caused by the ferrous ions in the ferrous ammonium sulfate solution, which get oxidized to ferric ions in the process. The overall reaction involves a transfer of electrons from the iron(II) ions to the chromium(VI) ions, resulting in the observed color change.
What is oxidized during the oxidation stage of cellular respiration?
Glucose is. In cell respiration, the carbon atoms of glucose are oxidized.
Do reduced molecules have more energy than oxidized molecules?
No, oxidized molecules have more energy than reduced molecules.
Which species were oxidized or reduced in HCl?
chlorine was oxidized while oxygen was reduced to form hydrochloric acid.
Is succinic acid oxidized or reduced in the citric acid cycle?
Succinic acid is oxidized in the citric acid cycle. It is converted to fumaric acid in a reaction that involves the transfer of electrons to the electron carrier FADH2. This process generates energy in the form of ATP.

Is carbon dioxide reduce or oxidized i photosynthesis?
Water is oxidized in the process of photosynthesis.
Is Zn oxidized or reduced?
Oxidized.
Which of the following is an electrolytic cell A. lron * (ll) * (Fe) oxidized, aluminum (Al) reduced O B. Silver (Ag) oxidized, gold (Au) reduced C. Aluminum () oxidized (Zn) reduced LithiumD. (Li) oxidized, (Zn) reduced?
The answer is not c.
Is fad oxidized or reduced?
yes
Is an electron donor an oxidized substrate?
yes it is oxidized substrate reduces itself and oxidize others
What is oxidized during the oxidation stage of cellular respiration?
Glucose is. In cell respiration, the carbon atoms of glucose are oxidized.
Is nadh oxidized or reduced compared to nad plus?
NADH is reduced compared to NAD+ because it gains electrons and a hydrogen ion to form NADH during cellular respiration. In this process, NAD+ acts as an electron carrier that accepts electrons and a hydrogen ion from substrates being oxidized, converting it to NADH.
When electroplating sliver on iron what is oxidized?
The iron is oxidized and the silver is reduced.
When a molecule is reduced and when a molecule is oxidized?
A molecule is reduced when it gains electrons or hydrogen atoms, resulting in a decrease in its oxidation state. Conversely, a molecule is oxidized when it loses electrons or hydrogen atoms, leading to an increase in its oxidation state. This process often involves the transfer of electrons between molecules in redox reactions, where one molecule is oxidized and another is reduced simultaneously.
Do reduced molecules have more energy than oxidized molecules?
No, oxidized molecules have more energy than reduced molecules.
What reactant is oxidized in respiration?
The reactant that is oxidized in respiration is glucose. Glucose is broken down through a series of biochemical reactions to release energy in the form of ATP, and in the process, it loses electrons, which is characteristic of oxidation.
