With ions shown as spheres and solvent molecules omitted
Chapter 4, Problem 30P(choose chapter or problem)
With ions shown as spheres and solvent molecules omitted for clarity, the circle (right) illustrates the solid formed when a solution containing \(\mathrm{K}^{+}, \mathrm{Mg} 2^{+}, \mathrm{Ag}^{+} \text {, or } \mathrm{Pb}^{2+}\) (blue) is mixed with one containing \(\mathrm{ClO}_{4}^{*}, \mathrm{NO}_{3}^{*} \text {, or } \mathrm{SO}_{4}{ }^{2-}\) (yellow).
Identify the solid.
Write a balanced net ionic equation for the reaction.
If each sphere represents \(5.0 \times 10^{-4} \mathrm{~mol}\) of ion, what mass of product forms?
Equation Transcription:
K+, Mg2+, Ag+, or Pb2+
ClO4-, NO3-, or SO42-
5.0 x 10-4 mol
Text Transcription:

ANSWER:
Solution 30P:
Step 1: (a)
Here, we have to identify the solid which is formed.
Given Cations: K+, Mg2+, Ag+, or Pb2+
The anions are :,
The possible products are :
Thus, the K salts of chlorate, nitrate and sulfate are soluble in aqueous medium.
The possible products of Mg2+ are :
Thus, the Mg salts of chlorate, nitrate and sulfate are also soluble in aqueous medium.
The possible products of Ag+ are :
Among all, only is insoluble in water.
Similarly,
The possible products of Pb2+ are :
Among all, only is insoluble in water.
Therefore, the solid products would be either or
But, according to figure, all the ions are precipitates as a product.
Therefore, the solid product is .
