Question
Chapter 7, Problem 44P
Interpretation Introduction
Interpretation: pH for lime juice from following options should be determined.
Concept Introduction: The pH defines the acidity of a substance. Acids have pH value less than 7 and bases have pH more than 7. As per some properties of acids and bases, they can also be differentiated on the basis of taste such as, acids are sour in taste and bases are bitter in taste. Also, higher the acidity lower will be the pH value.

Explain why the data points for the beaker lie roughly on a straight line. What kind of relationship is this? How do you know?
(see page 276 text) the design of the beaker is a uniform cylinder
the volume of liquid increases evenly with its height
resulting in a linear relationship.
What volume would you predict for 10.0 cm of water? Explain how you arrived at your answer. Use the data table and the
graph to assist you in answering the question.
4. Plot the volume of rain in milliliters versus its height in centimeters for the 250 mL Florence flask on the same graph. Draw a
best-fit curve through the points and label it "250 mL Florence flask."
