Consider the following statement:
`S_(1)`:`Cu^(2+)` ions are reduced to `Cu^(+)` by potassium iodide and potassium cyanide both, when taken in excess
`S_(2)`:`H_(2)S` will precipitate the sulphide of all the metals from the solutions of chlorides of `Cu,Zn` and `Cd` if the solution is aqueous.
`S_(3)`:The presence of magnesium is confirmed in qualitative analysis by the formation of a white crystal
`S_(4)` :Calomel on reaction with potassium iodide gives red precipitate.
and arrange in the order of true/false.
