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?
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.
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.
To determine which of the given reactions is not an example of a neutralization reaction, we first need to understand what a neutralization reaction is.
A neutralization reaction is a chemical reaction between an acid and a base, producing a salt and water. In this type of reaction, the hydrogen ions (H+) from the acid react with the hydroxide ions (OH-) from the base to form water (H2O), while the remaining ions combine to form a salt.
Let's analyze each given reaction to see if it fits the characteristics of a neutralization reaction:
A. HCl + NaOH → NaCl + H2O
This reaction involves an acid (HCl) reacting with a base (NaOH) to produce a salt (NaCl) and water (H2O). It follows the characteristics of a neutralization reaction.
B. 2 NaOH + H2CO3 → Na2CO3 + 2 H2O
This reaction involves a base (NaOH) reacting with an acid (H2CO3) to produce a salt (Na2CO3) and water (H2O). It also follows the characteristics of a neutralization reaction.
C. H2SO4 + 2 NH4OH → (NH4)2SO4 + 2 H2O
This reaction involves an acid (H2SO4) reacting with a base (NH4OH) to produce a salt ((NH4)2SO4) and water (H2O). It is also an example of a neutralization reaction.
D. 2 AgNO3 + Zn → 2 Ag + Zn(NO3)2
This reaction does not involve an acid and a base reacting with each other. It is a single displacement reaction in which zinc (Zn) displaces silver (Ag) from silver nitrate (AgNO3). Therefore, it is not an example of a neutralization reaction.
Based on our analysis, the reaction that is not an example of a neutralization reaction is option D: 2 AgNO3 + Zn → 2 Ag + Zn(NO3)2.
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.
