Question: Name the following ionic compounds: (a) \(\mathrm{HCl}(a q)\) (b) \(\mathrm{HClO}_{3}(a q)\) (c) \(\mathrm{Fe}_{2}\left(\mathrm{SO}_{3}\right)_{3}\) (d) \(\mathrm{Ba}\left(\mathrm{NO}_{2}\right)_{2}\) (e) \(\mathrm{NaClO}\) Answer: (a) Hydrogen Chloride (b) Hydrogen Chlorate (c) Iron(III) Sulfite (d) Barium Nitrite (e) Sodium Hypochlorite

Step by step solution

01

(a) Name of \(\mathrm{HCl}(a q)\)

To name this compound, we need to identify each ion. In this case, the ions are \(\mathrm{H^+}\) and \(\mathrm{Cl^-}\). \(\mathrm{H^+}\) is known as the hydrogen ion and \(\mathrm{Cl^-}\) is called the chloride ion. Combining the names of these ions, we get \(\mathrm{Hydrogen \ Chloride}\). Therefore, the name of the ionic compound \(\mathrm{HCl}(a q)\) is Hydrogen Chloride.
02

(b) Name of \(\mathrm{HClO}_{3}(a q)\)

In this compound, the ions are \(\mathrm{H^+}\) and \(\mathrm{ClO_3^-}\). We have already identified \(\mathrm{H^+}\) as the hydrogen ion. \(\mathrm{ClO_3^-}\) is called the chlorate ion. Combining the names of these ions, we get \(\mathrm{Hydrogen \ Chlorate}\). Therefore, the name of the ionic compound \(\mathrm{HClO}_{3}(a q)\) is Hydrogen Chlorate.
03

(c) Name of \(\mathrm{Fe}_{2}\left(\mathrm{SO}_{3}\right)_{3}\)

In this compound, the ions are \(\mathrm{Fe^{3+}}\) and \(\mathrm{SO_3^{2-}}\). \(\mathrm{Fe^{3+}}\) is called the Iron(III) ion (since iron can have multiple oxidation states, we need to include the oxidation state, in this case, 3+). \(\mathrm{SO_3^{2-}}\) is called the sulfite ion. Combining the names of these ions, we get \(\mathrm{Iron(III) \ Sulfite}\). Therefore, the name of the ionic compound \(\mathrm{Fe}_{2}\left(\mathrm{SO}_{3}\right)_{3}\) is Iron(III) Sulfite.
04

(d) Name of \(\mathrm{Ba}\left(\mathrm{NO}_{2}\right)_{2}\)

In this compound, the ions are \(\mathrm{Ba^{2+}}\) and \(\mathrm{NO_2^-}\). \(\mathrm{Ba^{2+}}\) is called the barium ion and \(\mathrm{NO_2^-}\) is called the nitrite ion. Combining the names of these ions, we get \(\mathrm{Barium \ Nitrite}\). Therefore, the name of the ionic compound \(\mathrm{Ba}\left(\mathrm{NO}_{2}\right)_{2}\) is Barium Nitrite.
05

(e) Name of \(\mathrm{NaClO}\)

In this compound, the ions are \(\mathrm{Na^+}\) and \(\mathrm{ClO^-}\). \(\mathrm{Na^+}\) is called the sodium ion and \(\mathrm{ClO^-}\) is called the hypochlorite ion. Combining the names of these ions, we get \(\mathrm{Sodium \ Hypochlorite}\). Therefore, the name of the ionic compound \(\mathrm{NaClO}\) is Sodium Hypochlorite.
