A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom are near ...

We can measure the rate of the reaction by measuring how fast the ... reacts with dilute hydrochloric acid to produce sodium chloride, water, sulfur dioxide and sulfur. The sulfur makes the ...

As the attractions from the water molecules and their motion pulls the ions apart, the sodium chloride crystal dissolves. The positive areas of the water molecules surround the negative Chloride ions.
