The pH scale is a measure of acidity/alkalinity and provides information about how substances tend to act in aqueous solutions. All living processes occur in an ideal pH range. Buffers act together to keep the pH within a certain range, based off the release or absorption of hydrogen ions.Ch...
The pH scale is used to determine whether a substance is acidic or basic, and to calculate how strong a chemical it is. A pH value is a number that ranges from 1 to 14 for most common chemicals, with seven being the middle or neutral point. Values below 7 are indicators of acidity, ...

pH stands for the "power of hydrogen" and is calculated by taking a negative logarithm from the molar concentration of the hydrogen ion in the solution. At 25 degrees Celsius, the equilibrium constant of water self ionization reaction is 10−14 which is the basis for the scale rang...

pH measurement is an important parameter in nearly every water quality application. In environmental sampling and monitoring, high or low pH values can be indicative of pollution. To determine the pH of water, a pH meter can be used to measure this impor
pH indicators are added to various acid/base solutions to determine the pH or hydronium ion concentration of solutions; the indicators function by undergoing a color change at or near a particular pH value.Answer and Explanation: An indicator is typically a weak acid that relinquishes its ...
Neurons that participate in sensory processing often display “ON” responses, i.e., fire transiently at the onset of a stimulus. ON transients are widespread, perhaps universal to sensory coding, yet their function is not always well-understood. Here, w
The C-terminal domain (CTD) of the largest subunit of RNA polymerase II (Pol II) is a regulatory hub for transcription and RNA processing. Here, we identify PHD-finger protein 3 (PHF3) as a regulator of transcription and mRNA stability that docks onto Pol II CTD through its SPOC domain...
The role of the diversity of shelter volumes provided by specific growth forms in structuring associated biodiversity and ecosystem functioning at the reefscape scale is yet to be fully understood and, above all, quantified. This could considerably enhance the evaluation of the potential of a reef...
