A one liter buffer is typically made from 60 millimoles of monoprotonated glycine ( H A ) and 10 millimoles of deprotonated glycine ( A ); these are salts of the diprotic amino acid glycine. Unfortunately you have run out of all forms of glycine. At you ...
The volumetric process of determining the concentration of an unknown sample by reacting it with another solution of known concentration is called titration. In an acid-base titration, a pH-volume curve or titration curve represents the change in the pH throu...
A mixture of the copper salt precursor (55.734 mmol/l), 1-octadecanethiol (0.683 mmol/l), 1-octanethiol (5.224 mmol/l), octadecylamine (0.683 mmol/l), 3-mercaptopropionic acid (0.64 mmol/l) in benzyl alcohol was prepared in a round-bottomed flask. Tribological properties of protic ionic li...
Ascorbic acid (vitamin C, C_6H_8O_6 ) is a diprotic acid ( Ka_1= 8.00X10^{-5} and Ka_2= 1.60X10^{-12} ). What is the pH of a 0.240 M solution of ascorbic acid? In chemistry, what is a formula used to represent? What is the definition of osmosis? Describe the structu...
