The video explores the concept of basic substances, focusing on their chemical properties and uses. It introduces super bases, which have a high affinity for hydrogen ions, and discusses their potential dangers. The pH scale is explained as a measure of base strength, with examples of how bases interact with water. The video highlights the record-breaking super base ortho-diethynylbenzenedianion and its ability to deprotonate water. Practical applications of super bases, such as sodium hydride, are also covered, showcasing their role in chemical reactions and hydrogen storage.

What is a characteristic of a chemical base?

• It is neutral on the pH scale.

• It has a low affinity for hydrogen ions.

• It has a high affinity for hydrogen ions.

What is a common use for bases like sodium hydroxide?

• Making soap

• Producing electricity

• Neutralizing water

• Creating acids

How does the pH scale measure the strength of a base?

• By the color change in a solution

• By the number of hydroxide ions present

• By the temperature of the solution

• By the amount of light absorbed

What happens when a super base deprotonates water?

• It forms a neutral solution.

• It releases hydrogen ions.

• It completely reacts with water.

• It becomes acidic.

What is one proposed use for sodium hydride?
