    HCl + NaOH  —>  NaCl + H₂O  ;   or; write as:

    NaOH + HCl   —>  H₂O + NaCl  .

            This type of "double-replacement" reaction is called "neutralization".
 
             Since we are adding a strong acid to a strong base (reactants), we know that the product will be:  1) a salt ; and 2) water.  Since we know one of the reactants will be "water" (H₂O) ; we can find the base (i.e. , the "remaining product") from selecting the "unused elements" to form the corresponding "salt".
