What effect does dilution have regarding the buffer system's pKa as compared to the literature value of pKa?
What effect does dilution have regarding the buffer system's pKa as compared to the literature value...
In the case of phosphate buffer, what are the correlation between buffer ph, pKa of the weak acid, and the maximum amount of buffer capacity? What are we expect to see in the "buffer capacity vs initial ph" plot? Does change the concentration of the buffers affect buffer capacity at a given Ph? why?
What relationship does buffer capacity versus buffer concentration have?
Phosphoric acids have three pKa. You can find their value from appendix 11 in the textbook (2.148, 7.199, 12.35) . Calculate the pH of a buffer that is 0.10 M in KH2PO4 and 0.050 M in Na2HPO4. What is the pH after adding 5.0 mL of 0.20 M HCl to 0.10 L of this buffer?
What effect do mergers and acquisitions have on future financial performance? Is there a balance sheet and income statement effect; if so what is/are they and do they help or hurt performance indicators? What effect does a merger or acquisition have on stockholder wealth? ie: Is there a potential for dilution of the stockholder’s net percentage of ownership? Does this activity have an effect on corporate strategy and strategic planning? If so then what are the issues and effects for...
