Question
Chapter 25.4, Problem 25.12P
Interpretation Introduction
(a)
Interpretation:
The product formed when the protein reacts with the excess of an acid needs to be determined.
Concept Introduction:
The proteins act as buffer for the body and they do not let the overall pH of the body to go beyond a certain limit and this happens due to the carboxylate anion and ammonium cations.
Interpretation Introduction
(b)
Interpretation:
The structure formed needs to be drawn when the protein reacts with excess base.
Concept Introduction:
The protein acts as a buffer for the body and maintains the pH of the body by means reacting with bases and acids. The carboxylate ion reacts with the acids and the ammonium end of the protein reacts with base or the nucleophiles.

- Comparing two means. Horvat and co-workers used atomic absorption spectroscopy to determine the concentration of Hg in coal fly ash. Of particular interest to the authors was developing an appropriate procedure for digesting samples and releasing the Hg for analysis. As part of their study they tested several reagents for digesting samples. Their results using HNO3 and using a 1+3 mixture of HNO3 and HCl are shown here. All concentrations are given as ppb Hg sample. HNO3: 161, 165, 160, 167, 166 1+3 HNO3–HCl: 159, 145, 140, 147, 143, 156 Determine whether there is a significant difference between these methods at the 95% confidence interval.arrow_forwardComparison of experimental data to “known” value.
