Three beakers labelled as A, B and C each containing 25 ml of water were taken. A small amount of NaOH, anhydrous CuSO4 and NaCl were added to the beakers A, B and C respectively. It was observed that there was an increase in the temperature of the solution contained in beakers A and B, whereas in case of beaker C, the temperature of the solution falls. Which one of the following statement(s) is (are) correct?
- a)In beakers A and B, exothermic process has occurred.
- b)In beakers A and B, endothermic process has occured.
- c)In beaker C exothermic process has occurred.
- d)In beaker C endothermic process has occurred.
Correct answer is option 'A,D'. Can you explain this answer?

Explanation:
Given Information:
- Beaker A contains NaOH.
- Beaker B contains anhydrous CuSO4.
- Beaker C contains NaCl.
- Each beaker initially contains 25 ml of water.
Observations:
- In beakers A and B, the temperature of the solution increases.
- In beaker C, the temperature of the solution decreases.
Explanation:
Exothermic and Endothermic Reactions:
- An exothermic reaction releases heat energy to the surroundings, resulting in an increase in temperature.
- An endothermic reaction absorbs heat energy from the surroundings, resulting in a decrease in temperature.
Analysis:
- In beaker A, when NaOH is added to water, it undergoes a highly exothermic reaction. The dissolution of NaOH in water is highly exothermic, releasing a large amount of heat energy. This results in an increase in temperature in beaker A.
- In beaker B, when anhydrous CuSO4 is added to water, it undergoes an exothermic reaction. The hydration of anhydrous CuSO4 is an exothermic process, releasing heat energy. This results in an increase in temperature in beaker B.
- In beaker C, when NaCl is added to water, it dissolves in water, which is an exothermic process. However, the dissolution of NaCl is not as exothermic as the reactions in beakers A and B. Additionally, the dissolution of NaCl is an endothermic process as it requires energy to break the ionic bonds between Na+ and Cl- ions. This energy absorption results in a decrease in temperature in beaker C.
Conclusion:
- In beakers A and B, exothermic processes have occurred, resulting in an increase in temperature.
- In beaker C, the dissolution of NaCl is an exothermic process, but it is not as exothermic as the reactions in beakers A and B. Additionally, the dissolution of NaCl is an endothermic process, resulting in a decrease in temperature.
Therefore, the correct statements are:
a) In beakers A and B, exothermic processes have occurred.
d) In beaker C, endothermic process has occurred.
Given Information:
- Beaker A contains NaOH.
- Beaker B contains anhydrous CuSO4.
- Beaker C contains NaCl.
- Each beaker initially contains 25 ml of water.

Therefore, the correct statements are:
