While the small intestine is the primary site for nutrient absorption, about 20% of alcohol is absorbed through the stomach lining before even reaching the small intestine. The stomach's unique acidic environment and highly permeable mucous membrane also allow for the direct absorption of certain medications and weak acids, answering the common question: what three things are absorbed through the stomach?.

In chemistry, the most alkaline salts are formed from the reaction of a strong base with a weak acid. This process, known as salt hydrolysis, is key to understanding their high pH levels. Here we explore precisely what are the most alkaline salts, detailing their formation and real-world applications.

According to the Arrhenius theory, an acidic substance releases hydrogen ions ($H^+$) in a solution. Electrolytes that are derived from or act as acids are thus classified as acidic electrolytes, playing a critical role in determining the pH of a solution.

Many common food items contain weak acids, which are responsible for their tangy flavors and preservative qualities. So, what foods contain weak acids? From citrus fruits and fermented dairy products to vinegar, these natural compounds are a staple in our diets.

Over 40% of all processed foods contain weak acids like citric and lactic acid for various purposes. So, are weak acids safe to use in food? The answer, for most people, is a definitive yes, as these substances are a crucial and regulated part of modern food production.
