What happens when H2SO4 reacts with KI?
What happens when H2SO4 reacts with KI?
KI reacts with H2SO4 producing I2 and H2S .
What is the product of H2SO4 Koh?
potassium sulfate
the word equation is: potassium hydroxide + sulfuric acid → potassium sulfate + water.
Does H2SO4 react with KOH?
Sulfuric acid react with potassium hydroxide to produce potassium sulfate and water.
Why is H2SO4 added to KI?
Because h2so4 is an oxidizing agent.it oxidizes HI which produced in the reaction of sulphuric acid and KI . as a result reaction between alcohol and HI to produce alkyl iodide cannot occur.
What happens when KI is heated?
Potassium iodide is a white crystalline salt with chemical formula KI, used in photography and radiation treatment. KI can turn yellow upon heating in air or upon standing in moist air for long periods, because of oxidation of the iodide to iodine.
When 50cm3 of 0.2 N H2SO4 is mixed with 50cm3 of 1N KOH the heat liberated is?
Also, their volumes will be equal as well that makes H2SO4, a limiting reactant to the solution. When 50cm3 of 0.2N H2SO4 is mixed with 50cm3 of 1N KOH heat liberated is 573 J.
What happens when KBr is heated with conc H2SO4?
Hint: KBr is an alkali metal halide. When it reacts with concentrated acid, we expect the halide to be liberated. Thus, the reddish-brown coloured gas we can see is of bromine. Elemental bromine does not occur freely in nature as it is highly reactive.
Is nh4i soluble?
Ammonium iodide is the chemical compound NH4I. It is used in photographic chemicals and some medications. It can be prepared by the action of hydroiodic acid on ammonia. It is easily soluble in water, from which it crystallizes in cubes.
What happens when ki is heated with H2SO4?
What happens when Ki is heated with h2so4? Potassium iodide react with sulfuric acid to produce potassium sulfate, iodine, hydrogen sulfide and water. The reaction takes place in a boiling solution. Click to explore further. Then, why is Sulphuric acid not used during the reaction with KI?
Is H2SO4 an oxidizing or a reducing agent?
It is always an oxidizing agent. In H2SO4 sulphur is in +6 oxidation state. To acta a reducing agentone should lose electrons i.e; the atom should go from lower positive oxidation state to higher positive oxidation state. So it can’t act as a reducing agent.
Which acid is prepared from Ki and phosphoric acid?
HI reduces sulphuric acid to sulphur dioxide and itself is oxidised to iodine. Hence, HI is prepared by heating KI with conc. phosphoric acid. Same is true for the preparation of HBr. Was this answer helpful? Which acid produces sugar charcoal from sugar?
