Ethylenediammonium ion refers to an organic compound with the chemical formula C₂H₄(NH⁺₃)₃. From its ammonia complex, its characteristics include:
- a pungent ammonia-like odor, and;
- it is a colorless liquid
The dissociation of a chemical compound(here, it's Ethylenediammonium) is the disintegration of a compound into simpler compounds or elements that may typically be recombined mostly under distinct conditions.
The dissociation of ethylenediammonium ion occurs in two stages and can be represented as follows:
1.\mathbf{NH_3^+ CH_2CH_2NH_3^+_{(aq)} \rightleftharpoons NH_2CH_2CH_2NH_3^+_{(aq)}+H^+_{(aq)}}
From above, the formation of hydrogen ion H⁺ indicates that ethylenediammonium ion is an acid.
Thus, in the first dissociation, the equilibrium constant can be represented as: \mathbf{Ka_1}
\mathbf{NH_3^+ CH_2CH_2NH_3^+_{(aq)} \rightleftharpoons^{\mathbf{Ka_1}} NH_2CH_2CH_2NH_3^+_{(aq)}+H^+_{(aq)}}
2.
The second stage of the dissociation can now be expressed as:
\mathbf{NH_2 CH_2CH_2NH_3^+_{(aq)} \rightleftharpoons ^{\mathbf{Ka_2}} NH_2CH_2CH_2NH_2_{(aq)}+H^+_{(aq)}}
From above, we will notice that the equilibrium constant is \mathbf{Ka_2}
Thus, from the above explanation, we can see the complete two acid dissociation reactions for ethylenediammonium ion and the correct symbol for the equilibrium constant for each reaction.
