Question

For each of the following, write the expected chemical formula.a. Aluminum ion and bromide ion :b. Strontium ion and hydroxide ion :c. Iron (III) ion and oxide ion :d. Calcium ion and phosphate ion :e. Ammonium ion and nitrate ion :

Answer 1

The expected formulas for these ions are:

a. Aluminum ion and bromide ion:

`\begin{gathered} Aluminum\text{ ion: }Al^(+3) \\ Bromide\text{ }ion:Br^(-1) \end{gathered}`

b. Strontium ion and hydroxide ion:

`\begin{gathered} Strontium\text{ ion}:\text{ Sr}^(+2) \\ Hydroxide\text{ ion}:OH^- \end{gathered}`

c. Iron(III) ion and oxide ion

`\begin{gathered} Iron(III)\text{ }Ion:Fe^(*3) \\ Oxide\text{ }ion:O^(-2) \end{gathered}`

d.Calcium ion and phosphate ion

`\begin{gathered} Calcium\text{ }ion:Ca^(+2) \\ Phosphate\text{ }ion:PO_4^(-3) \end{gathered}`

e.Ammonium ion and nitrate ion

`\begin{gathered} Ammonium\text{ ion:}NH_4^+ \\ Nitrate\text{ ion }:NO_3^- \end{gathered}`
