Question

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?

Answer 1

When 2 molar equivalents of HCl are added to a solution of 1,2-diaminoethane, the resulting ionic compound is H3NC2H4Cl-.

Step-by-step explanation:

When 1,2-diaminoethane, H2NCH2CH2NH2, dissolves in water, it forms a basic solution. When 2 molar equivalents of hydrochloric acid (HCl) are added to a solution of 1,2-diaminoethane, the resulting ionic compound is a salt called 1,2-diaminoethanium chloride, or H3NC2H4Cl-.

Answer 2

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).
