Answer to Question #256752 in General Chemistry for Spongey

Question

A mixture is first made of 150 cm3 of a 0.200 mol.dm–3 solution of silver nitrate and ycm3 of a 2.50 mol.dm–3 solution of potassium cyanide. Thereafter, 100 cm3 of a 0.120 mol.dm─3 solution of potassium chloride is added to this mixture and the resulting solution is diluted to 2.00 dm3 . Calculate the value of y that will just prevent the precipitation of silver chloride.

Answer 1

150*0.2/100*0.12=30/12=2.5
