Answer:

The result is the formation of an aqueous solution of ordinary table salt (sodium chloride), an equimolar amount of water, and lots of heat. This exothermic reaction, especially if the reactants are in concentrated solutions (well above 1 M are possible with each) gives off so much heat it will likely cause the reaction mixture to explosively boil. Even if the reaction doesn’t boil, the reaction vessel frequently becomes dangerously hot.
