Consider the reactions :
`2S_(2)O_(3(aq))^(2-)+I_(2(s))rarrS_(4)O_(6(aq))^(2-)+2I_((aq))^(-)`
`S_(2)O_(3(aq))^(2-)+2Br_(2(l))+5H_(2)O_((l))rarr 2SO_(4(aq))^(2-)+4Br_((aq))^(-)+10H_((aq))^(+)`

Consider the reactions 2S_(2)O_(3)^(2-)(aq)+I_(2)(s)toS_(4)O_(6)^(2-)(aq)+2I^(-)(aq) S_(2)O_(3)^(2-)(aq)+2Br_(2)(l)+5H_(2)O(l)to2SO_(4)^(2-)(aq)+4Br^(-)(aq)+10H^(+)(aq) Why does the same reductant, thiosulphate react differently with iodine and bromine ?

Thiosulphate reacts differently with iodine and bromine in the reactions given below 2S_(2)O_(3)^(2-) +I_(2)rarrS_(4)O_(6)^(2-)+2I^(-) S_(2)O_(3)^(2-)+2Br_(2)+5H_(2)O rarr 2SO_(4)^(2-) +2Br^(-) +10H^(+) Which of the following statements in correct ?

For the reaction 2H_(2)O_((l)) rarr H_(3)O_((aq))^(+) + OH_((aq))^(-) , the value of Delta H is

Write the equation for rthe rate of the reaction 5 Br_((aq))^(-)+BrO_(3(aq))^(-)+6H_((aq))^(+)to 3Br _((aq))+3H_(2)O_((l))

Consider the reactions : a) H_(3)PO_(2)(aq)+4AgNO_(3)(aq)+2H_(2)O(l)toH_(3)PO_(4)(aq)+4Ag(s)+4HNO_(3)(aq) b) H_(3)PO_(2)(aq)+2CuSO_(4)(aq)+2H_(2)O(l)toH_(3)PO_(4)(aq)+2Cu(s)+H_(2)SO_(4)(aq) c) C_(6)H_(5)CHO(l)+2[Ag(NH_(3))_(2)]^(+)(aq)+3OH^(-)(aq)toC_(6)H_(5)COO^(-)(aq)+2Ag(s)+4NH_(3)(aq)+2H_(2)O(l) d) C_(6)H_(5)CHO(l)+2Cu^(2+)(aq)+5OH^(-)(aq)to no change is observed. What inference do you draw about the behaviour of Ag^(+)andCu^(2+) from these reactions?
