Balancing Redox Reactions in Basic Medium

The video tutorial explains how to balance chemical reactions in basic medium, starting with an introduction to balancing in both acidic and basic mediums. It details the steps to balance reactions using hydroxide ions to neutralize hydrogen ions, resulting in water formation. The tutorial concludes with a balanced reaction and offers additional resources for further learning on redo reactions.

What is the initial step in balancing a redox reaction in basic medium?

• Directly balance the charges

• Balance it in acidic medium first

• Add hydroxide ions to both sides

• Add water molecules to both sides

How can you convert a balanced acidic reaction to a basic one?

• By adding hydroxide ions

• By adding more reactants

• By changing the temperature

• By removing water molecules

What happens when hydroxide ions are added to hydrogen ions in a reaction?

• They form hydrogen gas

• They form hydroxide radicals

• They form water molecules

• They form oxygen gas

Why is it necessary to add hydroxide ions to both sides of the reaction?

• To increase the reaction rate

• To maintain charge balance

• To decrease the reaction rate

• To change the reaction medium

What is the result of neutralizing hydrogen ions with hydroxide ions?

• Formation of H2O

• Formation of H2

• Formation of O2

• Formation of OH-

What should be checked to ensure a reaction is balanced in basic medium?

• The balance of atoms and charges

• The pH level of the solution

• The temperature of the reaction

• The color of the solution

What indicates that a reaction is balanced in basic medium?

• Presence of excess H+ ions

• Presence of excess OH- ions

• Equal number of atoms and charges on both sides

• Formation of a precipitate

What is the significance of having hydroxide ions in the reaction?

• It indicates a neutral medium

• It indicates a basic medium

• It indicates an acidic medium

• It indicates a gaseous medium
