Question

Sodium reacts with oxygen to produce sodium oxide which dissolves in water to form sodium
hydroxide. On adding hydrochloric acid to the base solution, salt and water are produced. Write
balanced chemical equations to represent all the chemical reactions stated in the question. [5]​

Answer 1

Explanation:

• NaoH+Hcl=Nacl+H2o
• This reaction is called double displacement reaction and neutralisation reaction

Answer 2

Answer:

NaOH(AQ) + HCl(AQ) ---------- NaCl(AQ) + H2O(L)

Explanation:

The reaction here is double displacement. This reaction is specially known as neutralization reaction. Here the salt is Sodium Chloride (NaCl). The term AQ means aqueous and the term L means liquid. If any more doubt, you can ask me.
