Q1

When \(Cu ^{2+}\) ion is treated with \(KI\), a white precipitate, \(X\) appears in solution. The solution is titrated with sodium thiosulphate, the compound \(Y\) is formed. \(X\) and \(Y\) respectively are

a

\(X = Cu _2 I _2\) \(Y = Na _2 S _4 O _5\)

b

\(X = Cu _2 I _2\) \(Y = Na _2 S _4 O _6\)

c

\(X = CuI _2\) \(Y = Na _2 S _4 O _3\)

d

\(X = CuI _2\) \(Y = Na _2 S _4 O _6\)
