Question

Which statement is correct about the reaction that occurs between sodium hydroxide and hydrochloric acid?

Answer 1

Answer

Hi, the correct answer is,

B. It is an acid-base reaction because the sodium hydroxide base reacts with the hydrochloric acid to form a salt and water

Explanation

When an acid reacts with a base, the products are salt and water.In this case, sodium hydroxide is a base which contains hydroxide ions, OH-, whereas hydrochloric acid is an acid that has Hydrogen ions, H+.When they react, they form sodium chloride, NaCl in aqueous solution as the salt , and additional water molecules. The equation is;

NaOH (aq) + HCl (aq) → NaCl (aq) + H2O (l)

Answer 2

Answer:

It is an acid-base reaction because the sodium hydroxide base reacts with the hydrochloric acid to form a salt and water.

Step-by-step explanation:

The equation for the reaction is

NaOH  +  HCl  ⟶ NaCl  +  H₂O

base   +  acid ⟶  salt   + water

Thus, Option B is correct.

Options A and C are wrong, because a single displacement involves an element as one of the reactants. This reaction involves two compounds.

Option D is wrong. This is an acid base reaction because the hydrogen and hydroxide ions react with each other to form water.
