6) A solution of sodium chloride (molecular weight 58.5) is electrolyzed and it is found that a current of 1 A liberates 1.3 x 10-3 kg of chlorine (atomic weight 35.5) in one hour. Sodium chloride crystals of density 2.17 x 103 kg/m3 are analyzed by x rays and the unit cell parameter is found to be 5.6 x 10-10 m. From these data calculate the charge on a monovalent ion. 7) In a Milikan oil-drop experiment, a certain droplet...

A solution containing a mixture of lactic acid and lactate was found to have a pH of 3.56. Calculate the ratio of the lactate concentration to the lactic acid concentration in this solution.

During exercise when the body lacks an adequate supply of oxygen to support energy production, the pyruvate that is produced from the breakdown of glucose is converted into lactate. High lactate levels can lead to acidity in the muscle cells as some of the lactate hydrolyzes to lactic acid. The dissociation of lactic acid to lactate is shown in the reaction below. Lactic acid has a pKa of 3.86. A solution containing a mixture of lactic acid and lactate was found to...
