Question

During science lab, Jacob mixes together sodium hydroxide (NaOH) and hydrochloric acid (HCl). The two chemicals react to form sodium chloride (NaCl) and water (H2O).
Which of the following are reactants in the chemical reaction described above?

Answer 1

Answer: NaOH and HCl are the reactants for the reaction described.

Explanation:

Reactants of a chemical reaction is defined as the substances which take part in a chemical reaction and undergoes a chemical change. These are written on left side of the arrow.

Products are defined as the substance which are formed at the end of the chemical reaction. These are written on the right side of the arrow.

For the reaction of sodium hydroxide and hydrochloric acid, the equation represents:

$NaOH+HCl\rightarrow NaCl+H_2O$

Here, NaOH and HCl are reactants.

The above reaction is a type of neutralization reaction.

Answer 2

NaOH(sodium hydroxide) and HCl( hydrogen chloride) are reactants.
