At what relative humidity with `Na_(2)SO_(4)` be deliquescent (absorb moisture) when exposed to the air at `0^(@ )C` ? Given
`Na_(2)SO_(4).10H_(2)O(s) hArr Na_(2)SO_(4)(s) +10H_(2)O(g), K_(p)=4.08xx10^(-25)` and vapour pressure of water at `0^(@)C =4.58` Torr ?

Na_(2)SO_(4).10H_(2)O(s)hArrNa_(2)SO_(4).5H_(2)O(g) K_(P)=2.43xx10^(-8) atm^(5) incorrect statement is-

Na_(2)SO_(3)+H_(2)O_(2) rarr Na_(2)SO_(4) +H_(2)O , in reaction

Na_(2)b_(4)O_(7)10H_(2)O is

Na_(2)O_(2) + H_(2)SO_(4) to

Na_(2)CrO_(4)+HCl to H_(2)Cr_(2)O_(7)+Na_(2)SO_(4)

Na_(2)CrO_(4)+HCl to H_(2)Cr_(2)O_(7)+Na_(2)SO_(4)

Na_(2)CrO_(4)+HCl to H_(2)Cr_(2)O_(7)+Na_(2)SO_(4)

Equilibrium constants are given (in atm) for the following reactions at 0^(@) C. SrCl_(2).6H_(2)O(s) hArr SrCl_(2).2H_(2)O(s) + 4H_(2)O(g) , K_(p) = 5 xx 10^(-12) Na_(2)HPO_(4). 12H_(2) O(s) hArr Na_(2) HPO_(4). 7H_(2) O(s) + 5H_(2)O(g), K_(p) = 2.43 xx 10^(-13) Na_(2) SO_(4).10H_(2)O(s) hArr Na_(2) SO_(4) (s) + 10 H_(2) O(g), K_(p) = 1.024 xx 10^(-27) The vapour pressure of water at 0^(@) is 4.56 torr. At what relative humidity will Na_(2) SO_(4) be deliquescent (ie., absorb moisture when exposed to the air) at 0^(@) C ?
