Does anyone know what it is?

In the scientific way?

It is how acid or alakaline something is.

pH is a measure of the acidity or alkalinity of a solution. Aqueous solutions at 25°C with a pH less than seven are considered acidic, while those with a pH greater than seven are considered basic (alkaline). When a pH level is 7.0, it is defined as 'neutral' at 25°C because at this pH the concentration of H3O+ equals the concentration of OH− in pure water. pH is formally dependent upon the activity of hydronium ions (H3O+),[1] but for very dilute solutions, the molarity of H3O+ may be used as a substitute with little loss of accuracy.[2] (H+ is often used as a synonym for H3O+.) Because pH is dependent on ionic activity, a property which cannot be measured easily or fully predicted theoretically, it is difficult to determine an accurate value for the pH of a solution. The pH reading of a solution is usually obtained by comparing unknown solutions to those of known pH, and there are several ways to do so.

The concept of pH was first introduced by Danish chemist S. P. L. Sørensen at the Carlsberg Laboratory[3] in 1909. The name, pH, has claimed to have come from any of several sources including: pondus hydrogenii, potentia hydrogenii (Latin),[4] potentiel hydrogène (French), and potential of hydrogen (English).[5]

No.this is what I heard..They joined with PH company. I was on there the other day and it said they were joining together. =D
