This reaction is an explosive reaction of a strong acid combining with a strong base.
\[ \text{H}_2\text{SO}_4 + 2\text{NaOH} \rightarrow 2\text{H}_2\text{O} + \text{Na}_2\text{SO}_4 \]
Which compounds are the reactants and which are the products?
A.
Reactants: \(\text{H}_2\text{SO}_4 + 2\text{NaOH}\)
Products: \(2\text{H}_2\text{O} + \text{Na}_2\text{SO}_4\)
B.
Reactants: \(2\text{NaOH} + \text{Na}_2\text{SO}_4\)
Products: \(\text{H}_2\text{SO}_4 + 2\text{H}_2\text{O}\)
C.
Reactants: \(2\text{H}_2\text{O} + \text{Na}_2\text{SO}_4\)
Products: \(\text{H}_2\text{SO}_4 + 2\text{NaOH}\)
D.
Reactants: \(\text{H}_2\text{SO}_4 + 2\text{H}_2\text{O}\)
Products: \(2\text{NaOH} + \text{Na}_2\text{SO}_4\)
Answer (3)
Reactants: H₂SO₄ + 2 NaOH Products: 2 H₂O + Na₂SO₄
The answer is A.
An easy way to think of it is What is being reacted together? (Reactants) This is anything on the left hand side of the arrow.
And what is being made (Product) so anything on the right side of the arrow.
For this question the answer is A.
The reactants in the given reaction are H 2 SO 4 and 2 NaOH , while the products are 2 H 2 O and Na 2 SO 4 . Therefore, the correct answer is option A. This is a neutralization reaction between a strong acid and a strong base.
