Acids And Bases Concepts Challenge

What we verified before publishing

AI-generated content may contain mistakes. Check the sources below before relying on important information.

The following claims were verified through Perplexity Sonar before the questions were finalised. The host can reference any of them during play:

• The pH scale is a logarithmic measure ranging from 0 to 14, where 7 is neutral, values below 7 are acidic, and values above 7 are basic.
• Acids are substances that donate hydrogen ions (protons) in a solution, while bases are substances that accept hydrogen ions or donate hydroxide ions.
• A neutralization reaction occurs when an acid and a base react to produce water and a salt.
• Acids typically taste sour and turn blue litmus paper red, whereas bases taste bitter, feel slippery, and turn red litmus paper blue.
• Each one-unit change on the pH scale represents a tenfold change in the concentration of hydrogen ions in a solution.
• Lemon juice contains citric acid, which gives it a sour taste and a pH value lower than 7.
• Baking soda, or sodium bicarbonate, is a common household base often used to neutralize acidic substances.
• Human stomach acid is primarily hydrochloric acid, which helps digest food and kill bacteria.
• Strong acids and strong bases dissociate completely in water, while weak acids and weak bases only partially dissociate.
• The pH of pure water at 25 degrees Celsius is 7, which is considered the neutral point on the pH scale.
