Why is Amount of Gas in One Test Tube Double the Amount in the Other?
In Activity 1.7, the amount of gas in one test tube is double the amount of gas in the other test tube due to the process of electrolysis. The chemical equation for the electrolysis of water and the process are discussed in detail below. Electrolysis refers to the decomposition of a substance by an electric current. Electrolysis of water is the process of decomposing water into oxygen and hydrogen gas using electricity by a process called electrolysis. It is also known as electrochemical water splitting. Hydrogen gas released in this reaction can be used as hydrogen fuel. Furthermore, the hydrogen gas can be remixed with oxygen to create oxyhydrogen gas, which is used in welding and other applications.
The chemical equation for the electrolysis of water can be written as:
2H2O(l) --> 2H2(g) + O2(g)
The equation implies that water consists of two parts of hydrogen and one part of oxygen. It is evident that the amount of hydrogen gas collected in one test tube is double that of the oxygen collected in the other test tube. Therefore, the required name of the gas is hydrogen.
What is Electrolysis?
Electrolysis is a process that uses an electric current to induce chemical reactions in an electrolyte. It involves the migration of ions toward the electrodes, where oxidation and reduction occur, resulting in the decomposition or transformation of the electrolyte into its constituent elements or ions. The overall chemical reaction in electrolysis depends on the specific electrolyte used. The flow of electric current drives the continuous process of oxidation and reduction at the electrodes, allowing the electrolyte to be decomposed into its constituent elements or ions.
Electrolysis has numerous applications in various industries, such as metal refining, electroplating, the production of chemicals, and energy storage through processes like water electrolysis to generate hydrogen gas.
Why is the Amount of Gas Collected in One of the Test Tubes in Activity 1.7 double the Amount Collected in the Other? Name this Gas
The amount of gas collected in one of the test tubes in Activity 1.7 is double the amount collected in the other due to the electrolysis of water. The name of the gas is hydrogen. The electrolysis of water involves the decomposition of water (H2O) into its constituent elements, hydrogen (H2) and oxygen (O2), using an electric current. The electrolysis of water has several applications, including the production of hydrogen gas for various industrial purposes, such as chemical manufacturing and water splitting.
