Question

What is the correct chemical formula for Fe3+ and P3-

Answer 1

Answer:

FeP, which is iron (III) phosphide.

Explanation:

Hello,

In this case, when iron (III) ion and phosphide ion react, the following compound is formed as the charges are exchanged to each other at the subscripts:

$Fe^{3+}+P^{3-}\rightarrow Fe_3P_3$

Yet, since the three could be simplified to 1 at both Fe and P, we obtain:

$Fe^{3+}+P^{3-}\rightarrow FeP$

Which is known as iron (III) phosphide.

Best regards.
