Question

Write an equation when hydrochloric acid neutralises sodium hydroxide

Answer 1

Hydrochloric acid(HCl) reacts with Sodium Hydroxide ( NaOH) to form a colourless aqueous solution of Sodium Chloride ( NaCl)salt.

HCl + NaOH → NaCl + H2O

Now as per the law of conservation of mass, mass is neither created nor destroyed in a chemical reaction. So, the equation should be balanced and in this case it is already balanced.

Final equation we have

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

Answer 2

Answer:

HCl + NaOH -------- NaCl + H₂O

Explanation:

Neutralization is a chemical reaction in which an acid reacts with the base to form a salt and water. Here, HCl is an acid that reacts with a base "NaOH" and thus produces Salt (NaCl) and water (H₂O). In this reaction, H+ and OH- and other cation and anion readily react with each other and form a salt and water molecule.
