Question Question 20
Conc. H2SO4 acts as a 'drying agent' & a 'dehydrating agent'. Explain and differentiate the words in italics.
| Drying agent | Dehydrating agent |
|---|---|
| The substances which can readily absorb or remove moisture from other substances are known as Drying agent. | The substances which remove chemically combined water or elements from compounds, due to their strong affinity for water are called Dehydrating agents. |
| Conc. sulphuric acid [as a drying agent] - absorbs only moisture from the substance and makes it dry without changing it's composition. | Conc. sulphuric acid [as dehydrating agent] - removes water molecule from the composition of substance and reacts chemically and produces a new substance with new properties. |
