NaCl HCl Reaction

If we tried to predict the product of the reaction between NaCl and HCl (Sodium chloride + Hydrochloric acid) we would expect there to be a double displacement reaction. Here the Na and H atom could switch places. • However, if the Na and H were to switch places we could end up with HCl and NaCl, the same compounds we started with. Because of this we say there is no chemical reaction taking place. • What is interesting is that if the NaCl solution is saturated (no more NaCl will dissolve) the addition of concentrated HCl will result in NaCl precipitating out of solution. This is because NaCl is less soluble than HCl. When we add HCl we are adding more Chloride ions (Cl-). This forces the Cl- ions in solution to combine with the Sodium ions (Na+) and form solid NaCl, which falls to the bottom of the beaker as a precipitate. This is called the Common Ion Effect . • You can see that happen in this video: • • Common Ion Effect • www.Breslyn.org
