Which of the following is not a salt that can be produced from an acid-base neutralization reaction? . cacl2. nh3. baf. na2so4

A acid -base neutralization is a reaction that produces water and a salt. The acid should be strong as well as the base. Cacl2 comes from Ca(OH)2 and HCl- Ca(OH)2 is a strong base, hence CalCl2 is a salt from this rxn. NH3 is not a salt. BaF comes from strong Ba(OH)2 and weak HF, hence not a salt from this rxn. Na2SO4 comes from strong NaOH and strong H2SO4. The answer is BaF. 

BaF is the one among the following options given in the question that is not a salt that can be produced from an acid-base neutralization reaction. The correct option among all the options that are given in the question is the third option It is important to note that salt and water is produced during acid-base neutralization reaction. I hope the answer comes to your help.

Ibelieve the answer is d

4- c, because all matter stays the same no matter what. it is still there. 5- b, because matter is known as mass. 6-c because, flammability is a chemical property. malleability is changing the shape of an object.
