Ückel equation is 0.866.
The Debye-Hückel equation relates the mean ionic activity coefficient (γ±) of an electrolyte to its molality (m) and temperature (T). The equation is:
log γ± = - A z1z2√(m)/(1 + B√(m))
where A and B are constants that depend on the solvent, z1 and z2 are the charges of the cation and anion, respectively.
For 0.001 molal ZnSO4 (aq) at 298 K, we have:
- z1 = +2 (for Zn2+)
- z2 = -2 (for SO42-)
- m = 0.001 mol/kg
- T = 298 K
- A = 0.5092 (for water at 25°C)
- B = 3.15 (for water at 25°C)
Substituting these values into the equation, we get:
log γ± = - (0.5092)(2)(-2)√(0.001)/(1 + 3.15√(0.001))
log γ± = - 2.652
γ± = 10^(-2.652)
γ± = 0.0019
Therefore, the mean ionic activity coefficient of 0.001 molal ZnSO4 (aq) at 298 K according to the Debye-Hückel equation is 0.0019 (rounded to three significant figures).
