The solubihty of AgI in NaI solution is less than that in pure water because
Agl forms complex with Nal
of common ion effect
solubility product of AgI less
the temperature of the solution decreases
Hydrogen ion concentration in mol/L in a solution of pH = 5.4 will be
3.98 × 108
3.88 × 106
3.68 × 10-6
3.98 × 10-6
D.
3.98 × 10-6
pH = -log[H+]
5.4 = -log[H+]
[H+]= antilog (-5.4) = 3.98 × 10-6
XY2 dissociated as XY2(g) XY(g) + Y (g) When the initial pressure of XY2 is 600 mm Hg, the total equilibrium pressure is 800 mm Hg. Calculate K for the reaction assuming that the volume of the system remains unchanged.

1
Iodide | PI3 | AsI3 | SbI3 |
Bond angle | 102 | 100°2' | 99° |
due to small size of P
due to more bp-bp repulsion in PI3
due to less electronegativity of P
None of the above
