Question

How many grams of precipitate are formed when 71 mL of 0.50 M FeCl3 reacts with excess AgNO3 in the following chemical reaction? FeCl3 (aq) + 3 AgNO3 (aq) + 3 AgCl (s) + Fe(NO3)3 (aq)

Answer 1

The reaction given here is a feelz + 3 AgNO3 (99) 3 Agel (3) + Fe(NO3), 2 (aq) The ppt of Age is formed. 1 mol of felly reacts with 3 mol of AgNO3 in normal condition. We have Il mi 0.5 (M) of Fell solution which reacts with excess AgNO3 solution. 71 mi 0.5 (M) Fecha solution 71405 mol 1000 = 0.0355 mol of Feelz.. So, 0.0355 mol of Fechy reacts with excess AgNO3. According to the reaction given from 1 mol Felly, 3 mol of Aga precipitate is formed i. From 0.0355 mol of Felly (0.0355 x3) = 0.1065 mol Agol is formed

... Age precipitate formed = 0.1065 mol. Molar mass of Agd = 143.32 gr/mol . Agu precipitate formed = (143-32 x 0 1065) gm. - 15:26358.gm . . 15. 26.358 gri of solid Aga preci- - pitate will torm.
