Video summaries: pH and pKa relationship for buffers
So if pH is equal to pKa then the concentration of A- over the concentration of HA is equal to one and the concentration of A- is equal...

In terms of the Henderson-Hasselbach equation, we can derive it by raising both sides to the 10th power and from here we can make three...
Video summaries: Buffers solution pH calculation
After writing the entire reaction we’ve got to finally use our Henderson-Hasselbach equation pH=9.25+Log 0.18/0.26= 9.09. Remembering...

The following problem is “if 0.03 mol of HCl added to 0.50 L of the buffer solution (0.24 M NH3 and 0.20 M NH4Cl), what is the resulting...
Video summaries: Buffers solution pH calculation
As sodium hydroxide is a base it is going to react with NH4Cl (acid): NH4’+ +OH- it’s going to product H2O+NH3. Now that we know the...

Our next problem says “If 0.005 mol of NaOH is added to 0.50 L of the buffer solution (0.24 M NH3 and 0.20 M NH4Cl), what is the...
Video summaries: Buffers solution pH calculation
Hello! Deriving the Henderson-Hasselbach equation we’ve got that pH=pKa+log (-A)/(HA); here we have a conjugate acid-base pair, HA the...
