1.	An element A burns with golden flame in air. It reacts with another element B, atomicnumber 17 to give a product C. An aqueous solution of product C on electrolysis gives acompound D and liberates hydrogenIdentify A,B,C also write down the equations for the reactionsinvolved
Answer» A is sodium (burns with golden flame), B is chlorine (atomic number 7), C is sodium chloride and D is sodium hydroxide. When sodium reacts with chlorine, it gives sodium chloride. Na + Cl ⇨ NaCl Electrolysis of sodium chloride gives sodium hydroxide. 2NaCl + 2H2O ⇨ 2NaOH + Cl2+ H2

Answer»

A is sodium (burns with golden flame), B is chlorine (atomic number 7), C is sodium chloride and D is sodium hydroxide.

When sodium reacts with chlorine, it gives sodium chloride.

Na + Cl ⇨ NaCl

Electrolysis of sodium chloride gives sodium hydroxide.

2NaCl + 2H2O ⇨ 2NaOH + Cl2+ H2
