Question

At 25 °C, only 0.0980 mol of the generic salt AB3 is soluble in 1.00 L of water What is the KsD of the salt at 25 °C? A3+(aq)

science chemistry

Answer 1

Answer #1

AB3 <-------------> A+3 (aq) + 3 B-(aq) is the solubility equilibria

If solubility =s

AB3 <-------------> A+3 (aq) + 3 B-(aq)

s 0 0 initial concentration

- s 3s equilibrium concntration

given solubility s = 0.0980mol/L

thus

the equilibrium constant , called [Ksp] solubility product

is given by

Ksp = [A+3] [B-]³

= [0.0980] [3x0.0980]³

=2.49x10^-3
