Many metals like copper, zinc, tin lead are refined by this method. 43. As the hydrogen ion Scheme of Question Paper S. No. Electrolysis of water is the process of using electricity to decompose water into oxygen and hydrogen gas. ICSE Solutions for Class 10 Chemistry – ElectrolysisICSE Solutions Selina ICSE Solutions APlusTopper.com provides ICSE Solutions for Class 10 Chemistry Chapter 6 Electrolysis for ICSE Board Examinations. The potential difference between the electrodes is the reason why the transfer of ions takes place. Transport of ions in the electrolyte in response to the potential difference between the electrodes ("drift") is largely restricted to the regions very close to the electrodes. Whenever an aqueous solution is subjected to the electrolytic process, water can undergo oxidation and reduction processes and may even become the dominated process in the experiment if a sufficient amount of … When the gas was passed through water, the solution obtained turned blue litmus red. (CBSE 2021 syllabus) (CBSE 2021 syllabus) In this course, we will explore types of chemical reactions (unit1), acids, and bases (unit2), why metals are awesome (unit 3), why Carbon is responsible for life (unit 4), and how we classify elements (unit5). We know that an electrolyte contains ions, which are charged. This is also known as ELECTROLYSIS. for example (1) Electrolysis of water is the decomposition of water into oxygen and hydrogen gas because of an electric current being passed through the water.
