In one industrial synthesis of ethanol, ethane is first dissolved in 95% sulphuric acid. In the second step, water is added and the mixture is heated. Outline the reaction involved. Strategy: Alkyl hydrogen sulphates are easily hydrolyzed to alcohols by heating with water.

one type of liquid contains 20% water and the second type of liquid contains 35% of water. A glass is filled with 10 parts of first liquid and 4 parts of second liquid.the water in the new mixture in the glass is : (a) 37% (b) 46% (c) 12(1)/(7)% (d) 24(2)/(7)%

Some bacteria obtain their energy by oxidising sulphur, producing sulphuric acid as a by-product. In the laboratory, or in industry, the first step in the conversion of sulphur to sulphuric acid is to produce sulphur dioxide. The sulphur dioxide is converted to sulphur trioxide, which reacts with water to give sulphuric acid. Name one catalyst used industrially which speeds up the conversion of sulphur dioxide to sulphur trioxide.

In the laboratory, or in industry, the first step in the conversion of sulphur to sulphuric acid is to produce sulphur dioxide. The sulphur dioxide is converted to sulphur trioxide, which reacts with water to give sulphuric acid. What is the name of the compound formed between sulphur trioxide and sulphuric acid?

In the laboratory, or in industry, the first step in the conversion of sulphur to sulphuric acid is to produce sulphur dioxide. The sulphur dioxide is converted to sulphur trioxide, which reacts with water to give sulphuric acid. Write the equation for the conversion of sulphur dioxide to sulphur trioxide. Why does this reaction supply energy?

Name the compound formed when ethanol is heated in excess of conc. sulphuric acid at 443K. Also write the chemical equation of the reaction stating the role of conc. sulphuric acid in it. What would happen if hydrogen is added to the product of this reaction in the presence of catalysts such as palladium or nickel?

Assertion (A): To dilute sulphuric acid, acid is added to water and not water to acid. Reason (R ): Specific heat of water is quite large.
