Question

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⁻]?

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⁻]?
