Acid-base accounting is a predictive geochemical method used to quantify the net acid-generating or acid-neutralizing potential of geological or waste materials, particularly in the context of acid ...

As a result of fossil fuel emissions, many freshwater bodies in eastern North America have become acidified. When combusted, fossil fuels release sulfur dioxide and nitrogen oxide, the precursors to ...

A legacy of acid rain has acidified forest soils throughout the northeastern US, lowering the growth rate of trees. In an attempt to mitigate this trend, in 1999 scientists added calcium to an ...

An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...
