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

A. VPO4

Step-by-step explanation:

Answer 2

Given that a mixture of two solutions has the following ions,
`Na^(+)`,
`PO_(4)^(3-)`,
`V^(3+)`, and
`Cl^(-)`. The products formed in the reaction would be NaCl and VPO
`_(4)`. As per the solubiltiy rules, all chloride salts are soluble, all phosphate salts are insoluble except those with
`Na^(+),K^(+) and NH_(4)^(+)`.

The equation representing the reaction of these ions:

`Na^(+)`(aq) +
`PO_(4)^(3-)`(aq)+
`V^(3+)`+
`Cl^(-)`-->
`VPO_(4)(s)+Na^(+)(aq)+Cl^(-)(aq)`

So, the insoluble product will be vanadium phosphate
`VPO_(4)`

Correct answer: a.
`VPO_(4)`
