Question

A metal 'A'burns vigorously in air. It reacts with other element 'B' and make common salt. The aqueous
solution of common salt on electrolysis gives a compound 'Cand liberates hydrogen gas. Identify A, B and
C. Write down a balanced equation of the electrolysis and also name this process​

Answer 1

Answer:NaCl+H2O =NaOH+HCl

NaOH+HCl------on electrolysis---NaOCl+H2

Explanation:a is sodium(Na)

B is HCl

A+B gives NaCl i.e common salt

Common salt salt on adding water gives NaOH and HCl

Its electrolysis gives NaOCl and H2.

Answer 2

Answer:

The correct answer is - A - Na (sodium), B- Cl (chlorine) and C- NaOCl.

Explanation:

Sodium or Na is a metal that burns when it comes in contact in air and it reacts with the element chlorine symbolize with Cl and make common salt or the table salt.

When the common salt dissolves in aqueous solution, electrolysis makes the compound NaOCl and hydrogen gas.

                              NaOH+HCl  → NaOCl+H2  (on electrolysis)

Thus, the correct answer is - A - Na (sodium), B- Cl (chlorine) and C- NaOCl.
