$I, II$ & $III$

Vedclass · Answer

(D) $I$) The stability of superoxide increases as the size of the alkali metal cation increases due to the stabilization of the large anion by the large cation. Thus,the order $NaO_2 $II$) The basic strength of alkaline earth metal hydroxides increases down the group as the solubility and ionic character increase. Thus,the order $Mg(OH)_2 $III$) The thermal stability of alkaline earth metal carbonates increases down the group as the electropositive character of the metal increases. Thus,the order $MgCO_3 Therefore,all three statements are correct.

Constituents	Percentage
$1$. $CaO$	$a$. $2-3\%$
$2$. $MgO$	$b$. $50-60\%$
$3$. $SiO_2$	$c$. $5-10\%$
$4$. $Al_2O_3$	$d$. $20-25\%$

Which of the following orders are correct against the stated property?
$I$) $NaO_2 < KO_2 < RbO_2 < CsO_2$ - stability
$II$) $Mg(OH)_2 < Ca(OH)_2 < Sr(OH)_2$ - basic strength
$III$) $MgCO_3 < CaCO_3 < SrCO_3$ - thermal stability
