Which of the following on addition will cause deep red colour to disappear ?
`(A) underset("Pale yellow")(Fe^(3+)(aq)) + underset("Colourless")(SCN^(-)(aq))hArr underset("Deep red")([Fe(CNS)^(2)](aq))`
`I. AgNO_(3)" "II.HgCl_(2)" "III.H_(2)C_(2)O_(4)" "`(oxalic acid)

Which of the follow ing on the addition will cause deep red colour to disappeared ? underset("pale yellow")(Fe_(aq)^(3+)) + underset("colourless")(SCN_(aq)^(-)) hArr underset("deep red")([ Fe (SCN) ]_(aq)^(2+))

The following reaction is at equilibrium , underset("Yellow")(Fe_((aq))^(3+))+ underset("Colourless")(SCN_((aq)))rArrunderset("Deep red")([Fe(SNC)]_((aq))^(2+)) K_(c)=([Fe(SCN)])/([Fe^(3+)][SCN]) In the above reaction , colour intensity of red colour can be increased by :-

The following reaction is at equilibrium , underset("Yellow")(Fe_((aq))^(3+))+ underset("Colourless")(SCN_((aq)))rArrunderset("Deep red")([Fe(SNC)]_((aq))^(2+)) K_(c)=([Fe(SCN)])/([Fe^(3+)][SCN]) In the above reaction , colour intensity of red colour can be increased by :-

The following reaction is at equilibrium , underset("Yellow")(Fe_((aq))^(3+))+ underset("Colourless")(SCN_((aq)))rArrunderset("Deep red") ([Fe(SNC)]_((aq))^(2+)) K_(c)=([Fe(SCN)])/([Fe^(3+)][SCN]) In the above reaction , colour intensity of red colour can be increased by :- (A) addition of KSCN (B) addition of oxalic acid which reacts with F e 3 + ions (C) addition of H g 2 + ions which react with S C N − ions (D)red colour intensity cannot be changed

Following equilibrium is set up when SCN^(-) ion is added to Fe^(3+) in aqueous solution : underset("Pale yellow")(Fe^(3+))" "+" "underset("Colour less")(SCN^(-))" "hArr" "underset("Deep red")([Fe(SCN)]^(2+)) When silver nitrate is added to the solution, AgSCN gets precipitate. What will happen to the equilibrium?
