The Buffer Report

Alright, I have found out what was needed in the discussion for the buffer thing.

I will just simplify it here so everyone will know what to write and expect.

A buffer will have a greater buffering capacity if the pKa value is closer to the pH of the buffer. The pKa value of the Tris-HCl is 8.30. The pKa for THCl will decline 0.03unit per degree celcius rise in temperature. So from this, you will know how to find the discussion for Experiment 4) i)pH and iii)temperature.

The higher the concentration of a buffer, the higher the buffering capacity.

Now all I need to know is, did anyone write down what the teacher wrote in the board that day. How much sucrose did you all add into the Tris-HCl that day? Please. Seriously need an answer.

Please tell me about it in the comment.
