Solve q23

Dear student,

A test tube containing 100 ml water is equipped with a temperature sensor. The initial temperature is 19.2 °C. 100 ml concentrated sulfuric acid is then added to the water. The temperature increases rapidly.

Adding concentrated sulfuric acid to water causes an immediate temperature increase (initial temperature: 19.2 °C)

Within 1 minute, the final temperature of 131.2 °C is reached, a change of +112 °C.

Final temperature: 131.2 °C (an increase of +112 °C)

Concentrated sulfuric acid distinguishes itself by its high affinity to water. Mixing the two components results in massive heat emission, which can be traced back to the exothermic production of various hydrates from the sulfuric acid.

regards
