pH Testing - wastewater treatment

A ,pH, of 7 is ,neutral,. Every whole unit of ,pH, change represents a ten-fold change in the hydrogen ion activity. For example, a ,pH, of 5 is ten times more active than a ,pH, of 6 and a ,pH, of 4 is one hundred times more active than a ,pH, of 6. As with any analytical test, you want to ,make, sure your results are accurate and precise.
