Which substances are always produced in an acid-base neutralization reaction?
The names of the products will depend in part on the acid/base theory being used. Arrhenius theory: acid + base –> salt + water Bronsted-Lowry theory acid + base –> conjugate acid + conjugate base The most common explanation of acid/base reactions in beginning chemistry classes is the Arrhenius theory. In that case the products will always be a salt and water. That is true regardless of whether the acid and base are strong or not. Strong acid/strong base HCl(aq) + NaOH(aq) –> NaCl(Aq) (the salt) + HOH (water) Strong acid/weak base HNO3(aq) + Al(OH)3(aq) –> Al(NO3)3(aq) (the salt) + HOH (water) Weak acid /strong base HC2H3O2(aq) + KOH(aq) –> KC2H3O2(aq) (the salt) + HOH (water) Weak acid/weak base H2C2O4(aq) + Zn(OH)2(aq) –> ZnC2O4(s) (the salt) + HOH (water) ========= Follow up ========= Even if a gas is produced, as in the decomposition of NaHCO3, there will still be a salt produced.
