Low-acid coffee refers to coffee that has a reduced level of acidic compounds or a higher pH compared to regular coffee. There is no standardized definition, but low-acid coffee is often classified as having a pH above 5.0, with some sources suggesting a threshold of 5.5. [ 1 ]
The chemical complexity of coffee is emerging, especially due to observed physiological effects which cannot be related only to the presence of caffeine. Moreover, coffee contains an exceptionally substantial amount of antioxidants such as chlorogenic acids, hydroxycinnamic acids, caffeine and Maillard reaction products, such as melanoidins. [3]
Phenolphthalein is often used as an indicator in acid–base titrations. For this application, it turns colorless in acidic solutions and pink in basic solutions. It belongs to the class of dyes known as phthalein dyes. Phenolphthalein is slightly soluble in water and usually is dissolved in alcohols in experiments.
The 2-mm-long coffee borer beetle (Hypothenemus hampei) is the most damaging insect pest of the world's coffee industry, destroying up to 50 percent or more of the coffee berries on plantations in most coffee-producing countries. The adult female beetle nibbles a single tiny hole in a coffee berry and lays 35 to 50 eggs.
An example of a base being neutralized by an acid is as follows. Ba(OH) 2 + 2 H + → Ba 2+ + 2 H 2 O. The same equation relating the concentrations of acid and base applies. The concept of neutralization is not limited to reactions in solution. For example, the reaction of limestone with acid such as sulfuric acid is also a neutralization ...

In living organisms, the pH of various body fluids, cellular compartments, and organs is tightly regulated to maintain a state of acid–base balance known as acid–base homeostasis. Acidosis , defined by blood pH below 7.35, is the most common disorder of acid–base homeostasis and occurs when there is an excess of acid in the body.
