Acids, Bases and Salts
A student accidently spilled concentrated H2SO4 on his hand. Before the teacher got to know, his friend washed his hands with water and also with soap but the burning sensation on hand still continued. His friend then rubbed solid sodium bicarbonate on his hand and then washed with water, finally the burning sensation is relieved. Answer the following questions based on the above situation (i) Mention the values shown by student’s friend. (ii) Can you recommend any other substance available in the laboratory which can be used instead of sodium bicarbonate? (iii) Write the chemical reaction involved in the treatment of acid burn with sodium bicarbonate.

Answer

(i) The values shown by the student’s friend include quick thinking, responsibility, and helpfulness. He acted promptly to help his friend by attempting to neutralize the acid and alleviate the burning sensation.

(ii) Another substance that can be used instead of sodium bicarbonate is calcium carbonate (CaCO₃), which is also a weak base and can help neutralize the acid.

(iii) The chemical reaction involved in the treatment of an acid burn with sodium bicarbonate is as follows:

2NaHCO₃+ H₂S0₄→ Na₂SO₄+ 2H₂O + 2CO₂
