Reaction of potassium astatide with concentrated sulfuric acid?
Wiki User
∙ 13y ago
KAt + H2SO4(conc) = KHSO4 + HAt displacement
then
.......HAt + .......H2SO4 = At2 + H2S which can be balanced as follows:
2At- = At2 + 2e ] * 4
8e + 8H+ + H2SO4 = H2S + 4H2O
overall is
8At- + 8H+ + H2SO4 = H2S + 4H2O + 4At2

Is it preferable to pour concentrated sodium hydroxide over sulfuric acid spilled on the floor?
No. The reaction of sodium hydroxide with sulfuric is more exothermic. And hence it is preferred to pour a solution of sodium bicarbonate or potassium bicarbonate in the case of spills.
What is the reaction between concentrated sulfuric acid with water?
H2SO4 --> HSO42- + H+.
What is the chemical reaction of potassium dichromate with sulfuric acid?
chromic acid
What is the balanced Reaction of sulfuric acid and potassium oxide?
K20 + h2so4 = k2so4 + h20
How do you get iodine from iodide?
Use an Oxidizer, such as acidified Hydrogen peroxide, acidified Potassium permanganate, Sulfuric acid (concentrated), etc.

What happen if the potassium permanganate solution drop to the water and add of concentrated sulfuric acid?
It will change colour and become purple
Is concentrated sulfuric acid a liquid?
Yes, concentrated sulfuric acid is a liquid.
Balanced equation between copper and sulfuric acid?
Cu + 2H2SO4 ---> CuSO4 + 2H2O + SO2 This reaction only happens when the sulfuric acid is hot and concentrated.
What happens when glucuse react with concentrated sulfuric acid?
The chemical reaction (a dehydration reaction) is:C12H22O11 + H2SO4 = 12 C + 11 H2O
What are the products of a neutralization reaction between sulfuric acid and a potassium hydroxide?
Potassium sulphate and water: H2SO4 + 2 KOH----------K2SO4 + 2H2O
Which reaction produces more pure oxygen which is not united with other elements solid potassium permanganate with hydrogen peroxide or solid potassium permanganate with Sulfuric acid with H2O2?
The reaction that produces more pure oxygen which is not united with other elements is solid potassium permanganate with hydrogen peroxide rather than solid potassium permanganate with sulfuric acid with H2O2.
What is the Equation for the reaction between potassium iodide and dilute sulfuric acid?
2ki+ h2so4 ----> k2so4 + 2hi
