The Henderson-Hasselbalch equation can be used to model these equilibria. It is important to maintain this pH of 7.4 to ensure enzymes are able to work optimally. [12] Life threatening Acidosis (a low blood pH resulting in nausea, headaches, and even coma, and convulsions) is due to a lack of functioning of enzymes at a low pH. [13]
Published values for log K 1 and log K D are 5.89 and 2.05, respectively. [2] Using these values and the equality conditions, the concentrations of the three species, chromate CrO 2− 4 , hydrogen chromate HCrO − 4 and dichromate Cr 2 O 2− 7 can be calculated, for various values of pH, by means of the equilibrium expressions.
At 25 °C (77 °F), solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic. Solutions with a pH of 7 at 25 °C are neutral (i.e. have the same concentration of H + ions as OH − ions, i.e. the same as pure water). The neutral value of the pH depends on the temperature and is lower than 7 if the temperature ...
A typical titration curve of a diprotic acid, oxalic acid, titrated with a strong base, sodium hydroxide.Both equivalence points are visible. Titrations are often recorded on graphs called titration curves, which generally contain the volume of the titrant as the independent variable and the pH of the solution as the dependent variable (because it changes depending on the composition of the ...
The pH after the equivalence point depends on the concentration of the conjugate base of the weak acid and the strong base of the titrant. However, the base of the titrant is stronger than the conjugate base of the acid. Therefore, the pH in this region is controlled by the strong base. As such the pH can be found using the following: [1]

Will Brigham Young come in behind Boise State? Almost definitely. No. 6 last Tuesday, the Cougars should land no higher than No. 13, one spot or more behind Boise State, after losing 17-13 to Kansas.
