Question

Write the ions present in solution of k2co3. express your answers as chemical formulas separated by a comma. identify all of the phases in your answers.

Answer 1

Answer : The ions present in the solution of $K_2CO_3$ are $K^+$ and $CO^{2-}_3$ in aqueous state.

Explanation :

When $K_2CO_3$ is in aqueous solution then they dissociates into their ions.

The reaction in aqueous medium is,

$K_2CO_3(aq)\rightarrow 2K^+(aq)+CO^{2-}_3(aq)$

The charge on potassium ion is +1 and on carbonate ion is -2. To neutralize the charge on carbonate ion, two potassium ion must be used.

Therefore, the ions present in solution of $K_2CO_3$ are $K^+$ and [tex]CO^{2-}_3[tex] in aqueous state.

Answer 2

$\boxed{{{\text{K}}^ + },\;{\text{CO}}_3^{2 - }}$ are the ions present in the solution of ${{\text{K}}_{\text{2}}}{\text{C}}{{\text{O}}_{\text{3}}}$ . Both ions are in the aqueous phase.

Further Explanation:

Chemical bond:

The attraction between atoms, molecules or ions which results in the formation of chemical compounds is known as a chemical bond. It is formed either due to electrostatic forces or by the sharing of electrons. There are many strong bonds such as ionic bonds, covalent bonds, and metallic bonds while some weak bonds like dipole-dipole interactions, London dispersion forces, and hydrogen bonding.

Ionic compound:

Ionic compounds are the compounds that are formed from the ions of the respective species. Ions are the species that are formed either due to loss or gain of electrons. A neutral atom forms cation by the loss of electrons and anion by the gain of electrons.

Following are some of the properties of ionic compounds:

1. These are hard solids.

2. High melting and boiling points.

3. Good conductors of heat and electricity.

4. High enthalpy of fusion.

For example, ${\text{MgC}}{{\text{l}}_2}$ is an ionic compound formed from one ${\text{M}}{{\text{g}}^{2 + }}$ and two ${\text{C}}{{\text{l}}^ - }$ ions. Its dissociation occurs as follows:

${\text{MgC}}{{\text{l}}_2}\rightleftharpoons {\text{M}}{{\text{g}}^{2+}}+{\text{2C}}{{\text{l}}^ - }$

${{\mathbf{K}}_{\mathbf{2}}}{\mathbf{C}}{{\mathbf{O}}_{\mathbf{3}}}$  is an ionic compound that consists of two ${{\mathbf{K}}^{\mathbf{ + }}}$ ions and one ${\mathbf{CO}}_{\mathbf{3}}^{{\mathbf{2 - }}}$ ion. Therefore it dissociates to form two ${{\text{K}}^ + }$ ions and one  ${\text{CO}}_3^{2 - }$ ion. The reaction for dissociation of  ${{\mathbf{K}}_{\mathbf{2}}}{\mathbf{C}}{{\mathbf{O}}_{\mathbf{3}}}$ is,

${{\text{K}}_2}{\text{C}}{{\text{O}}_3}\left({aq}\right)\to2{{\text{K}}^ + }\left( {aq} \right)+{\text{CO}}_3^{2 - }\left({aq}\right)$

So the ions present in ${{\text{K}}_2}{\text{C}}{{\text{O}}_3}$ solution are two ${{\text{K}}^ + }$ and one ${\text{CO}}_3^{2 - }$ ions. Both the ions are present in the aqueous phase.
