Question

Two solutions are mixed, bringing together ions of Na+, PO43−, V3+, and Cl−. Use the solubility rules to identify the composition of the salt that precipitates out of the solution. A. VPO4 B. Na3PO4 C. VCl3 D. NaCl

Answer 1

Correct answer is: A

Answer 2

Answer: The correct answer is Option A.

Step-by-step explanation:

We are given some ions, which are:
`Na^+,PO_4^(3-),V^(3+)\text{ and }Cl^-`

The compounds which may be formed from these ions will be
`Na_3PO_4,NaCl,VPO_4\text{ and }VCl_3`

Precipitates are defined as the substances which are not soluble in water at any temperatures. They remain undissolved in water.

Out of the formed salts, the soluble ones are
`Na_3PO_4,NaCl\text{ and }VCl_3`

`VPO_4` remains insoluble in water and thus, the correct answer is Option A.
