Fluorine is the best oxidising agent because it has :
highest electron affinity
highest Eored
highest Eooxid
lowest electron effinity
Bleaching action of SO2 is due to its :
oxidising property
acidic property
basic property
reducing property
D.
reducing property
SO2 act as bleaching agent due to its reducing property .
When I2 is passed through KCl , KF and KBr solutions :
Cl2 and Br2 are evolved
Cl2 is evolved
Cl2 , Br2 and F2 are evolved
none of the above
Assertion : Sb2S3 is not soluble in yellow ammonium sulphide.
Reason : The common ion effect due to S2- ions reduces the solubility of Sb2S3.
If both assertion and reason are true and reason is the correct explanation of the assertion.
If both assertion and reason are true but reason is not the correct explanation of the assertion.
If assertion is true, but reason is false.
Both assertion and reason are false statements.
