Based on the calculations, the solubility of PbCrO₄ in water at at 25°C is equal to 1.4 x 10⁻⁸ M.
<h3>How to calculate the solubility of PbSO₄?</h3>
The properly balanced chemical equation for the dissociation of PbSO₄ is given by:
PbCrO₄(s) ⇆ Pb²⁺(aq) + CrO₄²⁻(aq)
Initial 0 0
Change +x +x
Equib. conc. x x
<u>Note:</u> The Ksp of PbCrO₄ at 25°C is equal to 2.0 × 10⁻¹⁶.
Next, we would set up an equation from the ICE table for its Ksp;
Ksp = [Pb²⁺][CrO₄²⁻]
2.0 × 10⁻¹⁶ = [x][x]
2.0 × 10⁻¹⁶ = x²
x = √2.0 x 10⁻¹⁶
x = 1.4 x 10⁻⁸ M.

Answer:
D. The study of magnetic quality of ancient rocks
South Africa has a booming tourism industry that helped increase employment and market trade. To attract tourist, first, they opened their country with 90 days visa-free stay. Second, their promotion through their website. Third, they want the world to see the beauty of their nature and wildlife reserves, so they opened railways with luxuries coaches traveling across south Africa in 12-15 days. Fourth, they also offered other options like a plane ride to access their beautiful islands prominent with historical values. Lastly, they advertise popular native popular products like wines, by doing so, they also helped local farmers.
