Why is sodium ions reduced to na while calcium does not in the electrolysis of fused nacl infact both ions are present in it. cacl2 to lower the melting point of na?
its because the reduction potential of calcium is less than sodium
Why would bleach rust a steel screw?
A bleach is a chemical that removes color or whitens, often via oxidation. Common chemical bleaches include household "chlorine bleach", a solution of approximately 3-6% sodium hypochlorite (NaOCl). "Rusting", is an oxidization process. To indicate the easiness or hardness of the oxidation/reduction process, people use so-called "Standard Reduction Potentials", to show how it is. The more negative the number is, the easier it is to be oxidized and the harder it is to be reduced (back to metal). Vice versa, the more positive the number is, the harder it is to be oxidized and the easier it is to be reduced. For non-metal element, we also can assign the standard reduction potential such as: 2HClO(aq) + 2H+ + 2e− → Cl2(g) + 2H2O, +1.63V Cl2(g) + 2e− → 2Cl−(aq) +1.36V 2H+(aq) + 2e− → H2(g), 0.00V This indicate that bleach (+1.63V) is easy to be reduced, thus it would grab the electrons from something else. That is to say, it is a strong oxidizer to cause other metals to be oxidized. Even Cl2 formed as product still serves as a strong oxidizer (+1.36V). On the other hand, water, containing small amount of H+, is extremely weak oxidizer (with reduction potential of 0.00V).
Do metals prefer to be oxidized or reduced?
Metals all prefer to loose electrons (sodium -> Na+, Fe - > Fe3+ etc.) S they prefer to be oxidised (oxidation is electron loss).
What happens when phenol treated with sodium borohydride?
Oxidized yo aldehyde
What mechanism is involved in the reduction of Benzophenone to Diphenylmethanone?
This is a reduction mechanism and can be done using Zinc Dust or Sodium Borohydride

What substance is being oxidized when sodium reacts with chlorine gas?
Sodium is oxidized to Na+ ion and Chlorine is reduced to Cl- ion. Sodium chloride is the final product.
What is the reduction potential of sodium borohydride?
-1.24 v
What happens when sodium peroxide comes in contact with sodium thiosulfate?
An exothermic reaction will occur, with the peroxide being reduced and the thiosulfate being oxidized.
Why is sodium ions reduced to na while calcium does not in the electrolysis of fused nacl infact both ions are present in it. cacl2 to lower the melting point of na?
its because the reduction potential of calcium is less than sodium
What type of reaction is Na plus F2 NaF?
It is a REDOX reaction. Sodium is oxidized by Fluorine which is itself reduced by the sodium. 2Na + F2 = 2NaF.
Which is the least likely to be reduced Ni Fe Cu Na?
Sodium (Na) is least likely to be reduced. It is very easily oxidized as it will lose its valence electron with little difficulty.
Why sodium chloride is not in the aqueous state?
The reduction potential of sodium is under the same potential of water.
