In chemistry, a "buffer" is a solution you add to another solution in order to balance its pH, its relative acidity or its alkalinity. You make a buffer using a "weak" acid or base and its "conjugate" base or acid, respectively. To determine a buffer's pH–or extrapolate from its p...
TBE is generally more expensive than TAE and inhibits DNA ligase, which may cause problems if subsequent DNA purification and ligation steps are intended. With the three simple steps that follow, learn how to make TBE buffer. It shouldn't take more than about 30 minutes to create. What You ...
How Do You Make a Buffer? A buffer is made by mixing a large volume of aweak acidorweak basetogether with its conjugate. A weak acid and its conjugate base can remain in solution without neutralizing each other. The same is truefor a weak baseand itsconjugate acid. How Do Buffers Work?

Calculate the molal concentration of the solution that will be created after you add your solute to the solvent. For instance, consider a solution created by dissolving 0.5 moles of salt into 1 liter (L) of water. One liter of water has a mass of 1 kilogram (kg), so: ...
