Write down three equations of the reaction, during which you get Fe (NO3) 3.

Let us consider three chemical reactions as a result of which the formation of a salt of trivalent iron nitrate occurs.

The first reaction takes place between substances such as ferric chloride and silver nitrate salt. Two salts are formed, silver chloride, which precipitates, and ferric nitrate.

FeCl3 + 3AgNO3 = Fe (NO3) 3 + 3AgCl

2) The second reaction of obtaining ferric nitrate, occurs when the salt of iron sulfate and the salt of barium nitrate.

Fe2 (SO4) 3 + 3Ba (NO3) 2 = 2Fe (NO3) 3 + 3BaSO4 ↓

The third reaction is the interaction of iron bromide with silver nitrate.

FeBr3 + 3 AgNO3 = Fe (NO3) 3 + 3 AgBr ↓.

All three reactions proceed according to the type of exchange.
