Explanation:
Detailed explanation-1: -The sulfuric acid removes water from the sugar in a highly exothermic reaction, releasing heat, steam, and sulfur oxide fumes.
Detailed explanation-2: -Concentrated sulphuric acid is used for the dehydration of alcohol because sulphuric acid is a strong oxidizing agent. It also has a strong affinity toward water thus absorbing water. When concentrated sulphuric acid reacts with alcohol, it oxides some alcohol to carbon dioxide and reduces itself to sulphur dioxide.
Detailed explanation-3: -In this study, sulfuric acid was added to the tannin–sucrose adhesive as a catalyst to improve the curing process.
