Calculate the molar solubility of thallium chloride (TlCl)in 0.30 mol L^-1 NaCl(aq)at 25 °C.K_sp for TlCl(s)is

Question

Quizplus · Accepted Answer

We can use the following equation to calculate the molar solubility of TlCl:

Ksp = [Tl+][Cl-]

Let x be the molar solubility of TlCl, then we have:

Ksp = (x)(x) = x^2

Since we are given the concentration of NaCl, we can assume that the ionization of TlCl is negligible compared to NaCl, therefore [Na+] is approximately equal to [Cl-]. We can use the concentration of NaCl as the concentration of Cl-:

[Cl-] = 0.30 mol L-1

Substituting the values into the equation for Ksp, we get:

11ea7a5e_3e74_11f5_89bd_dfb3f1da36a5_TB5343_11 = x^2

x = 5.7 × 10-15 mol L-1

Therefore, the correct answer is B.
