The relation between pH and pK_{a} is as follows.
pH of the buffer is 3.44.
b)
mol of HCl added = 11.6M *0.001 L = 0.0116 mol
In the given reaction, will react with
to form
No. of moles of
And, no. of moles of
= 0.12 mol
after the reaction :
No. of moles of = moles present initially - moles added
= (0.15 - 0.0116) mol
= 0.1384 mol
Moles of = moles present initially + moles added
= (0.12 + 0.0116)
= 0.1316 mol
As,
Since, volume is both in numerator and denominator, we can use mol instead of concentration.
= 3.347+ log {0.1384/0.1316}
= 3.369
≅ 3.37
pH after the addition of 1.00 mL of 11.6 M HCl to 1.00 L of the buffer solution is 3.37
