$\ce{ch_{3}coo^{-}}$ (or $\ce{c_{2}h_{3}o_{2}^{-}}$) # $\ce{co_{3}^{2-}}$ # $\ce{clo_{3}^{-}}$ # $\ce{clo_{2}^{-}}$ # $\ce{cro_{4}^{2-}}$ # $\ce{cn^{-}}$ # $\ce{cr_{2}o_{7}^{2-}}$ # $\ce{hco_{3}^{-}}$ # $\ce{oh^{-}}$ # $\ce{clo^{-}}$ # $\ce{no_{3}^{-}}$ # $\ce{no_{2}^{-}}$ # $\ce{clo_{4}^{-}}$ # $\ce{mno_{4}^{-}}$ # $\ce{so_{4}^{2-}}$ # $\ce{so_{3}^{2-}}$

Explanation:

Step1: Identify the ion formula for sulfate

Sulfate ion has the formula \(SO_{4}^{2 -}\).

Step2: Identify the ion formula for nitrite

Nitrite ion has the formula \(NO_{2}^{-}\).

Step3: Identify the ion formula for chlorate

Chlorate ion has the formula \(ClO_{3}^{-}\).

Step4: Identify the ion formula for chromate

Chromate ion has the formula \(CrO_{4}^{2 -}\).

Step5: Identify the ion formula for dichromate

Dichromate ion has the formula \(Cr_{2}O_{7}^{2 -}\).

Step6: Identify the ion formula for hypochlorite

Hypochlorite ion has the formula \(ClO^{-}\).

Step7: Identify the ion formula for permanganate

Permanganate ion has the formula \(MnO_{4}^{-}\).

Answer:

ammonium: \(NH_{4}^{+}\)
sulfate: \(SO_{4}^{2 -}\)
nitrite: \(NO_{2}^{-}\)
phosphate: \(PO_{4}^{3 -}\)
chlorate: \(ClO_{3}^{-}\)
chromate: \(CrO_{4}^{2 -}\)
dichromate: \(Cr_{2}O_{7}^{2 -}\)
hypochlorite: \(ClO^{-}\)
permanganate: \(MnO_{4}^{-}\)
