When 1,2-diaminoethane, h2nch2ch2nh2, dissolves in water, the resulting solution is basic. write the formula of the ionic compound that is formed when 2 molar equivalents of hydrochloric acid (hcl) is added to a solution of 1,2-diaminoethane?

Because 1,2-diaminoethane is base, this compound gain protons from acid (in this example hydrochloric acid) and becaume ionic compound with positive charge (cation).

1,2-diaminoethane is organic compound and hydrochloric acid is inorganic compound.

Balance chemical reaction:

H₂NCH₂CH₂NH₂ (aq) + 2HCl (aq) → ⁺H₃NCH₂CH₂NH₃⁺ (aq) + 2Cl⁻ (aq).
