Question 2 calculate the ph of a solution that has an acetic acid concentration of 0.05 m and a sodium acetate concentration of 0.075 m. (a) by making use of the henderson - hasselbach equation. (b) without making any assumptions. (4) (6) 1101

Answer : The pH of the solution is, 4.9

Explanation : Given,

Dissociation constant for acetic acid =

Concentration of acetic acid = 0.05 M

Concentration of sodium acetate = 0.075 M

First we have to calculate the value of .

The expression used for the calculation of is,

Now put the value of in this expression, we get:

Now we have to calculate the pH of buffer.

Using Henderson Hesselbach equation :

Now put all the given values in this expression, we get:

Therefore, the pH of the solution is 4.9.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
