Abuffer is made by dissolving 11.6 g of sodium dihydrogen phosphate, nah2po4 (mr = 119.97701128 g/mol), and 20.1 g of disodium hydrogen phosphate, na2hpo4 (mr = 141.95884056 g/mol), in a liter of solution. what is the ph of the buffer? (assume ka for this equilibrium is 6.2 ✕ 10−8, and that kw is 1.0 ✕ 10−14.)

7.37 is the pH of the buffer.

Explanation:

To calculate the pH of acidic buffer, we use the equation given by Henderson Hasselbalch:

We are given:

= dissociation constant =

pH = ?

Putting values in above equation, we get:

7.37 is the pH of the buffer.
