Buffer Solution Ph 7.00 Potassium Dihydrogen Phosphate 500ml

A buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Suitable for laboratory use only. What is pH buffer used for? PH buffers are usually made up of a combination of a conjugate base and a weak acid that absorbs excess hydrogen atoms to retain a stable pH value in the solution. As such, they work well for calibrating electrochemical potentiometers for pH measurements with a low uncertainty to enhance traceability.13 Apr
