What happens when potassium reacts with water and oxygen?
When potassium reacts with water, it forms potassium hydroxide and releases hydrogen gas. When potassium reacts with oxygen, it forms potassium oxide.
Why HCl is used in titration of mohr salt and potassium dichromate?
Hydrochloric acid (HCl) is used in the titration of Mohr's salt and potassium dichromate because it reacts with Mohr's salt to form ferric chloride and with potassium dichromate to form chromium chloride. These reactions result in the formation of a color change in the solution which allows for the end point of the titration to be easily detected.
What is the chemical reaction of potassium dichromate with sulfuric acid?
When potassium dichromate reacts with sulfuric acid, the following reaction takes place: K2Cr2O7 + 2H2SO4 -> Cr2(SO4)3 + K2SO4 + 2H2O + 3O2. This reaction results in the formation of chromium(III) sulfate, potassium sulfate, water, and oxygen gas as products.
What happens when hexene reacts with cold neutral and dilute potassium dichromate?
One would expect that the reaction between an alkene and cold, dilute potassium dichromate is an oxidation to a bifunctional alcohol at the carbons in the double bond. The result is also called a vincinal diol or a glycol. The reaction should be similar to the reaction of an alkene with cold, dilute potassium permangante, however, dichromate is a milder oxidizing agent and may not be as effective. The mechanism for this reaction involves the formation of an intermediete 'ester' with the metal at the carbons of the double bond, breaking the double bond. The it can be shown that the resonance structure of the intermediete complex transfers electron density to the ester linkage and protonates from water at both of the ester sites completing the oxidation.
Chemical reaction between iron and potassium dichromate?
When iron reacts with potassium dichromate, iron(II) ion is oxidized to iron(III) ion by dichromate, which gets reduced to chromium(III) ion. The balanced chemical equation for this reaction is: 6 Fe^2+ + 14 H^+ + Cr2O7^2- --> 6 Fe^3+ + 2 Cr^3+ + 7 H2O
What colour change will occur when potassium dichromate reacts with ethanol?
Potassium dichromate is orange and when it reacts with ethanol which is a primary alcohol it is going to oxidise it to form aldehyde which is colorless. so the color change is from Orange to Colorless. :)
Which one is better for titration with Ferrous Ammonium Sulphate potassium dichromate or potassium permaganate and why?
Potassium dichromate is better for titration with ferrous ammonium sulfate because it reacts with ferrous ions in a 1:6 ratio, making it easier to determine the equivalence point accurately. Potassium permanganate, on the other hand, reacts with ferrous ions in a 1:5 ratio, which can lead to less precise results and requires a more careful technique.
What happens when potassium dichromate reacts with oxalic acid what is the name of the product?
When potassium dichromate reacts with oxalic acid, it undergoes a redox reaction where the dichromate ion is reduced to chromium(III) ion, and the oxalic acid is oxidized to carbon dioxide and water. The products of this reaction are chromium(III) oxide, carbon dioxide, and water.
What happens when potassium reacts with water and oxygen?
When potassium reacts with water, it forms potassium hydroxide and releases hydrogen gas. When potassium reacts with oxygen, it forms potassium oxide.

What happens to potassium in water?
It reacts violently, fizzes about on the surface and then: BOOM!!!
What is the equation opf the reaction between sodium ethanedioate and potassium dichromate?
The reaction between sodium ethanedioate (sodium oxalate) and potassium dichromate can be represented by the following balanced chemical equation: 3 Na2C2O4 + K2Cr2O7 + 4 H2SO4 → 3 Na2SO4 + K2SO4 + Cr2(SO4)3 + 8 CO2 + 7 H2O In this reaction, sodium ethanedioate reacts with potassium dichromate in the presence of sulfuric acid to form sodium sulfate, potassium sulfate, chromium(III) sulfate, carbon dioxide, and water.
What happens when copper metal reacts with potassium cyanide?
Copper metal is less reactive than potassium so it will not react with potassium cyanide.
