Question

Which of the following is not an example of a neutralization reaction?
	A	HCl + NaOH NaCl +H2O
	B	2 NaOH + H2CO3 Na2CO3 +2 H2O
	C	H2SO4 + 2 NH4OH (NH4)2SO4 + 2 H2O
	D	2 AgNO3 + Zn 2Ag +Zn(NO3)2

A?

No. Neutralization reactions are reactions between and acid and a base.
HCl is an acid in A. NaOH is a base. Neutralization reactions give a salt + water as products. You notice NaCl(a salt) and water. Try again.

How do you know which elements are acidic and which are bases?

I'm trying to compare the answer choices and D seems like it is different from the rest?

The Arrhenius theory helps. Acids have H^+ ionsin solution. Bases have OH^- ions in solution. Another thing you know is that when acids neutralize bases you get a salt + water (H2O) as the products. Which of those reactions DOES NOT give those products. That must be the one that is NOT an acid/base neutralization.

DrBob222 · Answer

That's right. A, B and C all have a salt + water as products so they are neutralization reactions between acids and bases. . The last one has Ag (an element) and Zn(NO3)2 (a salt) as products but no water. Also, neither Zn nor AgNO3 are acids or bases. No H^+ or OH^- in the reactants.
