PH is the acidity of the water.
>7.0 is acidic
7.0 is neutral
<7.0 is softer and less acidic *cant remember what is called right now though LOL *
had to look it up basisity is anything above 7.0
a buffer as said is the best way to change and maintain PH.
pH is the measure of the acidity or basicity of a solution. It is formally a measure of the activity of dissolved hydrogen ions (H+), but for very dilute solutions, the molarity (molar concentration) of H+ may be used as a substitute with little loss of accuracy.[1] In solution, hydrogen ions occur as a number of cations including hydronium ions (H3O+).[2]
In pure water at 25°C, the concentration of H+ equals the concentration of hydroxide ions (OH-). This is defined as "neutral" and corresponds to a pH level of 7.0. Solutions in which the concentration of H+ exceeds that of OH- have a pH value lower than 7.0 and are known as acids. Solutions in which OH- exceeds H+ have a pH value greater than 7.0 and are known as bases. 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 in 1909.[3] The name pH has been claimed to have come from any of several sources including: pondus hydrogenii, potentia hydrogenii (Latin),[4] potentiel hydrogène (French), and potential of hydrogen
