To determine the salt formed during a neutralization reaction, combine the anion formed by the dissociation of the acid and the cation formed by the dissociation of the base in a ratio that results in a neutral, ionic compound. For example, if you have a cation with a 1+ charge and an anion with a 2- charge, you will need two cations to balance the charge. [(1+ charge on cation)(2)]+[2 - charge on anion)(1)] = (+2) + (-2) = 0...
