=== Potential of Hydrogen (pH) ===

Every chemical has an innate pH, which can be seen by pressing the cog on the dispenser. The pH of the beaker is the sum of the pHes in the mix. The pH of a beaker determines how pure a product is, for the recipes with a given pH, you want to have your pH at the centre of the limits when the reaction starts. As a reaction progresses, it's likely the pH will begin to drift, and must be compensated for either with [[#Acidic_Buffer|buffer reagents]] or acidic/alkaline compounds. The pH range is something chemists often have to learn over several reactions, and the ChemMaster 3000 analyse function can give an insight into what pH you should be aiming for (Not in yet). Highly impure compounds are liable to affect your reaction too thus it is prudent to set your pH before reacting, as an overly impure reaction will drag the purity down of all other reagents with it. 

Presently the pH meter on the machines have a higher accuracy than normal to help players accumulate.
