HELLO FRIENDS........ANSWER THIS QUESTION.......Q1.GIVE THREE OBSERVATIONS DURING ELECTROLYSIS.BEST ANSWER will be marked as brainliest. |

Answer» ELECTROLYSIS of molten salts New substances form when a molten or dissolved ionic compound conducts electricity. For example, lead bromide can be used to produce bromine and lead using the following process: place solid lead(II) bromide in a crucible and heat over a Bunsen burner until it melts insert two carbon electrodes into the molten ELECTROLYTE and pass a direct current between them Carbon electrodes are chosen because they have a high melting POINT and are inert (they will not react with the reactants and products during electrolysis). The observations are summarised in the table: Anode (positive)Bubbles of brown gasBromine vapour (Br2) is producedCathode (negative)Silvery liquid metal present at this electrode underneath the remaining molten electrolyteLead (Pb) is produced It is easy to predict the products of electrolysis of molten electrolytes because they simply split into their elements: the metal is formed at the negative electrode because that is where the positive metal ions are attracted the non-metal ELEMENT is formed at the positive electrode where the negative non-metal ions are attracted For example: Zinc chlorideChlorineZincAluminium oxideOxygenAluminium Mark this answer as brainliest..!!
