The measured Ka value is 1.62 x 10^-5. Please help to solve questions 3 and 4. Thanks again
ull T-Mobile LTE 12:22 AM 17% C X e st pat of the lab, the following graph was produced. Absorbance Curves for BCG 0.6. basic form acidic form 0.5F 0.4 0.3 0.2 0.1 wavelength (nm) Wavelength of maximum absorbance for base form a. The graph shows that the basic form has a maximum absorption at Amax, while the acidic has its minimum absorption at Amax. Explain why the basic form and acidic form have opposite absorptions at this specific wavelength. What is the importance of determining the Ama? b. 3. The accepted K, value for Bromocresol green is 1.6 x 10. Using your measured value, determine the percent error. % error= Jaccepted-measured x 100 accepted 4. When we calculate the pH of the solutions it is found by using the following equation: pH =pk, + log (mol NaAc mel HAC Bromocresol green is a weak acid, just like acetic acid. But our calculations assume that bromocresol green does not affect the overall acidity (pH) of the acetate solution. Why is this a good assumption? Mixed (absorbance)
