Which is the strongest acid in the following?
H2SO4
HClO3
HClO4
HClO4
C.
HClO4
The strength of oxyacids can also be decided with the help of the oxidation number of the central atom. Higher the oxidation number of central atoms, more acidic is the oxyacid.
Since in HClO3 oxidation number of Cl is highest, so HClO4 is the strongest acid among the given.
Identify the correct order of solubility in aqueous medium
CuS> ZnS> Na2S
ZnS > Na2S> CuS
Na2S> CuS> ZnS
Na2S> CuS> ZnS

In Which of the following arrangement, the given sequence is not strictly according to the property indicated against it ?
HF < HCl< HBr < HI : increasing acidic strength
H2O < H2S < H2Se < H2Te : increasing pKa values.
NH3 < PH3 < AsH3 < SbH3 : increasing acidic character
NH3 < PH3 < AsH3 < SbH3 : increasing acidic character
The stability of +1 oxidation state among Al, Ga, In and TI increases in the sequence
Ga<In< Al<Tl
