Question

The [$$Pb^{2+}$$] and [AsO_{4}^{3−}] in a certain saturated Pb_{3}(AsO_{4})_{2} solution are both equal to 8.3×$$10^{−8}. In a $$saturated solution with [$$Pb^{2+}$$] = 0.020 M, what is [AsO_{4}^{3−}]?

Accepted Answer

7.0×$$10^{−16} M$$

Answer

2.1×$$10^{−11} M$$

Answer

7.1×$$10^{−12} M$$

Answer

3.5×$$10^{−16} M$$

The [Pb2+] and [AsO43−] in a certain saturated Pb3(AsO4)2 solution are both equal to 8.3×10−8. In a saturated solution with [Pb2+] = 0.020 M, what is [AsO43−]?

The [Pb²⁺] and [AsO₄³⁻] in a certain saturated Pb₃(AsO₄)₂ solution are both equal to 8.3×10⁻⁸. In a saturated solution with [Pb²⁺] = 0.020 M, what is [AsO₄³⁻]?
