Discover which foods are acidic or alkaline and the science behind the alkaline diet. Learn about their health impacts and the dietary recommendations for various foods.

The NYTimes article has an article today talking about the role of lactic acid and exercise. First up, I think the fault probably lies with the writer, not the scientist, for misrepresenting valid ...

A well-established technique, acid-base titration is an analytical method used to determine the concentration of an unknown acid or base. In practice, it involves adding a solution of known strength ...

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 ...

The pH scale is used to measure acidity and alkalinity levels. It measures the presence of positively and negatively charged hydrogen ions in a particular solution. The higher the hydrogen ions, the ...

This lab includes a theoretical explanation of how buffers work and how they are made, including a derivation of the Henderson-Hasselbalch equation. Students will use what they have learned to ...

The field of tumor microenvironment (TME) research has unveiled the crucial influence of acid–base dynamics in shaping cancer progression, metastatic ...

The pH is a negative logarithmic scale, which measures the molar concentration of hydrogen ions from 1 to 10 14 ions. It therefore has no unit of measurement. Numbers on a negative logarithmic scale ...

It is very important to separate and purify products from synthetic reaction mixtures. Extraction methods are used for separating the desired product from un-reacted starting materials or from ...
