The relationship between the buffer-component concentration ratio and the buffer range has to be given. Concept Introduction: Buffer solution: An aqueous solution consisting mixture of weak base and its conjugate acid or weak acid and its conjugate base. Its pH value changes very small when a small amount of strong base or an acid added to it. Buffer capacity: A quantitative measure of the resistance of a buffer solution to pH value change on the addition of hydrogen ion or hydroxide ion is known as buffer capacity. Buffering capacity = sum additions of acid or base change in pH value

Interpretation Introduction

Interpretation:

The relationship between the buffer-component concentration ratio and the buffer range has to be given.

Concept Introduction:

Buffer solution:

An aqueous solution consisting mixture of weak base and its conjugate acid or weak acid and its conjugate base. Its pH value changes very small when a small amount of strong base or an acid added to it.

Buffer capacity:

A quantitative measure of the resistance of a buffer solution to pH value change on the addition of hydrogen ion or hydroxide ion is known as buffer capacity.

Buffering capacity = sum additions of acid or basechange in pH value

3. 2. 1. On the graph below, plot the volume of rain in milliliters versus its height in centimeters for the 400 mL beaker. Draw a straight line through the points and label it "400 mL beaker." Volume (mL) 400 350 300 250 200 150 750 mL Florence Volume Versus Height of Water 400 mL beaker 100 50 0 0 2 3 4 5 Height (cm) 6 7 8 9 10 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.

In the video, we looked at the absorbance of a certain substance and how it varies depending on what wavelength of light we are looking at. Below is a similar scan of a different substance. What color BEST describes how this substance will appear? Absorbance (AU) Violet Blue Green Orange 1.2 1.0- 0.8- 0.6- 0.4- 0.2 0.0 450 500 550 600 650 700 Wavelength (nm) violet indigo blue green yellow orange red Red O Cannot tell from this information In the above graph, what causes -450 nm wavelength of light to have a higher absorbance than light with a -550 nm wavelength? Check all that are true. The distance the light travels is different The different data points are for different substances The concentration is different at different times in the experiment Epsilon (molar absortivity) is different at different wavelengths
