Question

a solution is a mixture of 0.06 M kcl and 0.06 M kI .agno3 is being addded untill agcl ppt .wt is conc of iodide?

Answer 1

K sp [ AgCl ] = [Ag + ] [ Cl- ]

As, Potassium chloride is strong electrolyte.  

[ KCl ] = [ Cl- ] = 0.06 M

[ Ag + ] = K sp [ AgCl ] / [ Cl- ]

= 1 x 10 ^ -10 / 0.06

K sp [ AgI ] = [ Ag + ] [ I - ]

[ I- ] = K sp [ Ag I ] / [ Ag + ]

= 4 x 10 ^ -16 x 0.06 / 10 ^ -10

= 2.4 x 10 ^ -7

Answer 2

Answer:

$2 \times {10 - }^{2}$
