The predominant form of ethylenediamine at pH 6.184 is H2NCH2CH2NH+3.

At pH 6.184, which is slightly acidic, the amino groups in ethylenediamine (H2NCH2CH2NH2) can partially protonate, resulting in the formation of ammonium ions (H+3NCH2CH2NH+3). The equilibrium between the neutral form and the protonated form is pH-dependent.

Therefore, at pH 6.184, the predominant form of ethylenediamine is H2NCH2CH2NH+3.
