Question

two methods of preparation of water gas​

Answer 1

Answer:

When Hydrogen gas react with oxygen gas,

we get water gas.

Answer 2

Answer:

Methods of preparation of water gas is given by

• By coke and steam process
• By the electrolysis of the water

Explanation:

• water gas, colorless poisonous gas that burns with an intensely hot, bluish (nearly colorless) flame. The gas is a mixture of carbon monoxide and hydrogen with very small amounts of other gases, e.g., carbon dioxide, and is almost entirely combustible as a result.
• Water-gas is so named because of the use of water (steam) in its preparation. This process involves treating white-hot hard coal or coke with a blast of steam; carbon monoxide and hydrogen are formed.
• The gas is manufactured in vast quantities for commercial use. It is of much importance in the preparation of hydrogen and as a fuel in the making of steel and in other industrial processes, e.g., the Fischer-Tropsch process.
• BY COKE AND STEAM PROCESS: When super heated is passed over red hot coke, a mixture of carbon monoxide and hydrogen is obtained which is known as water gas.
• BY THE ELECTROLYSIS OF WATER: When pure water containing a little amount of $H_{2}SO_{4}$or any ionic salt is electrolyzed, pure hydrogen is obtained.
