# Created a Potassium Phosphate Buffer | |||
## The original protocol asked to make the buffer using KH<sub>2</sub>PO<sub>4</sub> and 1M KOH | |||
## We opted to use the monobasic and dibasic species of the molecule to obtain the desired pH of 6.24 | |||
##* Calculations for the buffer were made using this website [[http://www.liv.ac.uk/buffers/buffercalc.html|The University of Liverpool Buffer Calculator]] | |||
To make the Potassium Phosphate buffer we used: | |||
