Systems pH control systems are known by their extreme rangeability and sensitivity, but contact between the measurement electrodes and hostile fluids can cause issues. Case studies of representative ...

New evidence uncovered by scientists at Johns Hopkins Medicine suggests that one root of Alzheimer's disease may be a simple imbalance in acid-alkaline—or pH—chemistry inside brain cells called ...

Soil pH or soil reaction is an indication of the acidity or alkalinity of soil and is measured in pH units. Soil pH is defined as the negative logarithm of the hydrogen ion concentration. The pH scale ...

Vinegar’s pH is low, meaning it’s acidic, but it can change if additional ingredients are added. If you dilute vinegar with water, its acidity lessens, making its pH level rise. The pH level of a ...

Saliva that is properly pH balanced (6.2 to 7.6) helps maintain a healthy mouth and protect your teeth. The acronym pH stands for potential hydrogen. It’s used to describe the chemical acidity level ...

Scientists say they have found new evidence in lab-grown mouse brain cells, called astrocytes, that one root of Alzheimer's disease may be a simple imbalance in acid-alkaline -- or pH -- chemistry ...
