Most popular drinks, including milk, juice, and coffee, contain 85% or more water, making the search for a truly waterless beverage a challenge. This article uncovers the rare liquid exceptions that contain no water, though they are often not hydrating or intended for consumption.

Dextrose and glucose are terms often used interchangeably, but a key chemical difference exists. Specifically, dextrose monohydrate is the hydrated form of D-glucose, meaning it is a D-glucose molecule that has one molecule of water attached.

Anhydrous substances, by definition, contain no water, a state more challenging to achieve in a natural environment than many might assume. This deep dive explores which does not contain water by examining various types of substances, from pure elements and dry compounds to refined oils and industrial gases.

The scientific truth about beef tallow is that, in its pure rendered state, it lacks a measurable pH. This is because pH is a measure of the hydrogen ion concentration in water-based solutions, and beef tallow is an anhydrous, or water-free, substance. Understanding this fundamental concept is key to debunking common myths, especially those related to its use in skincare.

The color of ferrous sulphate powder is not uniform and can range from bluish-green to white or yellowish-brown. This variation depends on its hydration state and exposure to air, making it a key indicator of the compound's properties.

The anhydrous form of calcium chloride ($CaCl_2$) contains approximately 36.1% elemental calcium by mass. Understanding the specific calcium content is crucial because the compound is often used in different forms, including its anhydrous state (without water) and various hydrated states (with water molecules attached). The total percentage of calcium varies depending on the amount of water present in the chemical structure.

Lactose, the primary sugar found in milk, can exist in several distinct forms, a fact crucial for its wide-ranging applications in the food and pharmaceutical industries. These variations, from its common crystalline state to less stable amorphous versions, dictate key physical properties like solubility, sweetness, and compressibility. Understanding these different forms is key to controlling the texture, shelf-life, and function of countless dairy and non-dairy products.

While virtually every common beverage, from juice to coffee, is primarily composed of water, a few substances are genuinely anhydrous, meaning they contain no water. A proper understanding of what drinks do not have water reveals that they serve specific, non-hydrating purposes and are not for general fluid intake.
