Answer to Question #135704 in General Chemistry for Burqa

Question

A water sample was tested and was found to contain ions of two varieties. Ion A is a smaller positive ion compared to ion B. When paired with CO3-2, the salt formed with A is having a ratio of 1:1, while for B, the anion-cation ratio is 1:2. This result was comparable to the pair of potassium sulfate and barium sulfate, and to that of lead (II) sulfate and lead (IV) sulfate.

2)Assuming that A and B are representative elements show the electron transfer and give the formulas of the compounds formed for both cations using the following anions: Br- and S-2. Explain the reason for such electron transfer.

Answer 1

When paired with CO3-2, the salt formed with A is having a ratio of 1:1, while for B, the anion-cation ratio is 1:2. This result was comparable to the pair of potassium sulfate and barium sulfate, and to that of lead (II) sulfate and lead (IV) sulfate.
