Concept: Balancing Chemical Reactions

Problem: Chlorine gas was first prepared in 1774 by C. W. Scheele by oxidizing sodium chloride with manganese(IV) oxide. The reaction isNaCl (aq) + H2SO4 (aq) + MnO2 (s) → Na 2SO4 (aq) + MnCl 2 (aq) + H2O (l) + Cl 2 (g)Balance this equation.

FREE Expert Solution

To balance equation → equal number of atoms on both sides → whole number coefficients


NaCl (aq) + H2SO4 (aq) + MnO2 (s) → Na2SO4 (aq) + MnCl2 (aq) + H2O (l) + Cl2 (g)

 

Balance Na and Cl:


4NaCl (aq) + H2SO4 (aq) + MnO2 (s) → 2Na2SO4 (aq) + MnCl2 (aq) + H2O (l) + Cl2 (g)


Balance H and O:


4NaCl (aq) + 2H2SO4 (aq) + MnO2 (s) → 2Na2SO4 (aq) + MnCl2 (aq) + 2H2O (l) + Cl2 (g)
