a buffer solution consists of a weak acid or base mixed with the salt of its conjugate base or acid, respectively. To calculate the specific pH of a given buffer, you need to use the Henderson-Hasselbalch
In this problem, we are interested in the relative concentrations of the acid (HF) and its conjugate base (F-). Step 2:Use the Henderson-Hasselbalch equation to calculate the relative quantities of the base and conjugate acid. Using the acid form of the equation, we can ...
To calculate the pH of an acid buffer, the Henderson-Hasselbalch equation is used, which is pH = pKa + log(acid/base). The acid's concentration is on top of the fraction, and the conjugate base's is on the bottom. What is the pH of a buffer? The pH of a solution, buffer or ...
Calculate the pH of a buffer that contains the following acid and conjugate base concentration of: HNO_2 = 0.029; NO_2^- = 0.065 The pKa of HNO_2 = 3.33. What is the pH of an aqueous solution of acetic acid (pKa = 4.76) if the ratio of conjugate base to conj...
Multiply the triangle semiperimeter by each value obtained in Steps 4 to 6. In the example, the equation would be: 15.94 x 8.23 x 5.69 x 2.02 = 1507.83 Step 8 Take the square root of the product from Step 7 to calculate the triangle's area. In the example, the area of the triangle...

Many software packages can calculate the background around your band of interest, using some variation of the “rolling ball” method (again, take time to understand your software). The background should be subtracted from both your bands of interest and the bands you are normalizing to. ...
