Kim Pupil performed this experiment and prepared a plot of lnP versus 1/T with a temperature scale ranging from 1/273 K to 1/353K.
Many scientists and business professionals describe the achievement as a turning point. Provide a summary of what took place during the project and why such activity is significant for us today.
there is no measurable difference between final and initial pH - that is why it is called a buffer E. final pH is 0.16 pH units lower than original pH
