Question

After carrying out the neutralisation reaction, the test tube immediately found to be somewhat hot. Explain why.

Answer 1

Answer:

If we touch the test-tube immediately after carrying out the neutralization reaction of an acid and a base in it, it is found to be somewhat hot. ... This is because some heat is evolved during the neutralisation reaction. This heat raises the temperature of reaction mixture and we feel the test tube hot.

Answer 2

Explanation:

What is an exothermic process?

• An exothermic process means energy release during the chemical reaction in the form of heat or light.
• Combustion, corrosion, neutralization, etc. are examples of exothermic reactions.

Why are the test tubes hot after the neutralization reaction?

• When neutralization reaction is carried out in a test tube, the formation of strong covalent bonds between hydroxide ions and hydrogens are taking place, and that's why it produces heat.

• This is called an exothermic process.
• So, the evolved heat makes the solution hot and eventually also makes the test tube hot immediately after the reaction.
