Q. 6.33 - An Introduction to General, Organic, and Biological Chemistry

Question

The following compounds contain ions that are required in small amounts by the body. Write the formula for each.

a. potassium phosphide

b. copper(II) chloride

c. iron (Ill) bromide

d. magnesium oxide

Step-by-Step Solution

Answer

The formulas are 

(part a)${\mathrm{SO}}_4^{2-}$,

(part b)${{\mathrm{CO}}_3}^{2-}$,

(part c)${\mathrm{HSO}}_3^{-}$,

(part d)${\mathrm{NO}}_3^{-}$

Step 1: Formula (Part a)

Sulfate ion is that the term for the ${\mathrm{SO}}_4^{2-}$ ion.

Step 2: Formula (Part b)

Carbonate ion is that the term for the ${{\mathrm{CO}}_3}^{2-}$ ion.

Step 3: Formula (Part c)

The formula of ${\mathrm{HSO}}_3^{-}$ion is  one atom greater than ${\mathrm{SO}}_3^{2-}$, sulphite ion. As a result, the hydrogen sulphite ion is thought as ${\mathrm{HSO}}_3^{-}$ ion.

Step 4: Formula (Part d)

The nitrate ion is known as ${\mathrm{NO}}_3^{-}$ion.
