1.	A solution of silver nitrate was stirred with iron rod will it cause any change in the concentration of silver and nitrate ions ?
Answer» Solution :Since `E^(@)` of `Fe^(2+)//Fe` (-0.44 V) is LOWER than that of `Ag^(+)//Ag(+0.80 V)` ELECTRODE therefore `Ag^(+)` gets REDUCED and Fe gets oxidised As a result concentration of `Ag^(+)` ions DECREASES while that of `NO_(3)^(-)` ions remains unchanged `2 Ag^(+) (aq)+Fe(s)rarr 2 Ag(s)+Fe^(2+)(aq)`
