pH and Buffer Solutions
13 cards
Card 1
Question: What does the pH value quantify?
Answer: The acidity or alkalinity of a solution.
Card 2
Question: What is considered a neutral pH?
Answer: A pH of 7.
Card 3
Question: What do pH values below 7 indicate?
Answer: Acidity.
Card 4
Question: What do pH values above 7 indicate?
Answer: Alkalinity (or basicity).
Card 5
Question: What does it mean for the pH scale to be logarithmic?
Answer: A change of one pH unit represents a tenfold change in hydrogen ion concentration.
Card 6
Question: How much more acidic is a solution with a pH of 3 compared to a solution with a pH of 4?
Answer: Ten times more acidic.
Card 7
Question: Why is stable pH vital in biological organisms?
Answer: Enzymes are highly sensitive to pH, and deviations can alter their structure and reduce or eliminate their activity.
Card 8
Question: Why is precise pH control necessary in chemical manufacturing?
Answer: To ensure reaction efficiency, product purity, and safety.
Card 9
Question: What is a buffer solution?
Answer: An aqueous solution that has the ability to resist significant changes in pH when small amounts of a strong acid or strong base are added to it.
Card 10
Question: What does a buffer solution typically consist of?
Answer: A mixture of a weak acid and its conjugate base, or a weak base and its conjugate acid.
