KCl3 + I2 → KI3 + Cl2
ICl + OH - → Cl- + IO -
CuI + Na2S2O3 → Cu2I2 + Na2S4O6 + NaI
Sn + HNO3 → SnO2 + NO2 + H2O

1st one is halogen exchange reaction naa ?bt i couldnt get 2nd one..
explain...

also in 4th it isnt mentioned dil or conc HNO3 so how do we know the products ??

actually for d 1st one, this reaction is not at all a redox reaction as the oxidation states of I and Cl donot change. its just like interhalogen displacement reaction.
and 4th one : actually,i think HNO3 both dil. and conc. have same products wid Sn, but in relative proportions.

thats what I said abt 1st reaction....halogen exchange reaction...
i asked u abt 2nd reaction
and in 4th when HNO3 conc is used then NO2 is produced and when HNO3 dil is used then NO is produced ..
what do u say ??

dude,in d 2nd one too , same thing happening as d 1st one. watch out . this reaction too is not at all a redox reaction as the oxidation states of I and Cl donot change. its too just like interhalogen displacement reaction.
in d 4th one: normally when NO is formed , it oxidises to NO2 wid atmospheric O2.thats why only, i said so.

nowhere . it ws an ionic reaction,thus i didn't write WATER. sry fr confusion.
