10^(-3) M Sr(C1O_(4))_(2) और 0.05 M KNO_(3) वाले घोल में केवल 75% पाया गया...

A solution containing 10^(-3) M Sr(C1O_(4))_(2) and 0.05 M KNO_(3) was found to have only 75% of its strontium in the uncomplexed Sr^(2+) form, the rest being Sr(NO_(3))^(o+) . Calcualate the K_(1) for complexation reaction: Sr^(2+) + NO_(3)^(Theta) rarr Sr (NO_(3))^(Theta)

Solubility of AgBr in water is S_(1), in "0.01 M "CaBr_(2) is S_(2) in 0.01 M NaBr is S_(3) and in 0.05 M AgNO_(3) is S_(4) . The correct order of these solubilities is :
