Question

100 ml , 0.25 M ionisation isomer of complex [ Co ( NH 3 ​ ) 5 ​ Cl ] Br reacts with excess of AgNO 3 ​ and gives x gm ppt. of compound Y . Calculate value of x in gm . [Given : Atomic weight in g mol -1 : Ag = 108, Cl = 35.5, Br = 80, Co = 59, N = 14, H = 1, O = 16]

TestHub · Accepted Answer

The complex is [ Co ( NH 3 ​ ) 5 ​ Cl ] Br . Its ionization isomer is [ Co ( NH 3 ​ ) 5 ​ Br ] Cl . This isomer reacts with AgNO 3 ​ to precipitate AgCl . Moles of isomer = 0.100 L × 0.25 M = 0.025 mol . Moles of AgCl formed = 0.025 mol . Molar mass of AgCl = 108 + 35.5 = 143.5 g/mol . Mass of AgCl (x) = 0.025 mol × 143.5 g/mol = 3.5875 g . Rounded to two decimal places, x = 3.59 g .
