An amphoteric substance is one that can act as an acid or as a base, depending on pH. Water (below) is amphoteric. Water (below) is amphoteric. Another example of an amphoteric molecule is the bicarbonate ion HCO − 3 that is the conjugate base of the carbonic acid molecule H2CO3 in the equilibrium
In Canada, regular beers typically have 5% ABV, while a reduced-alcohol beer contains 2.6%–4.0% ABV and an "extra-light" beer contains less than 2.5%. [ 21 ] In the United States, most mass-market light beer brands, including Bud Light , Coors Light , and Miller Lite , have 4.2% ABV, less than ordinary beers from the same makers which are 5% ABV.
The OE (Original Extract) is often referred to as the "size" of the beer and is, in Europe, often printed on the label as Stammwürze or sometimes just as a percent. In the Czech Republic, for example, common descriptions are "10 degree beers", "12 degree beers" which refers to the gravity in Plato of the wort before the fermentation.
In chemistry, an alcohol (from Arabic al-kuḥl 'the kohl'), [2] is a type of organic compound that carries at least one hydroxyl (−OH) functional group bound to a saturated carbon atom. [3] [4] Alcohols range from the simple, like methanol and ethanol, to complex, like sugars and cholesterol. The presence of an OH group strongly modifies the ...
An alcohol-free or non-alcoholic drink, also known as a temperance drink, is a version of an alcoholic drink made without alcohol, or with the alcohol removed or reduced to almost zero. These may take the form of a non-alcoholic mixed drink or non-alcoholic beer , and are widely available where alcoholic drinks are sold.
Quickly drinking 1.5 L of 0.4% alc/vol beer in an hour resulted in a maximum of 0.0056% BAC in a study of German volunteers. [8] Healthy human kidneys can only excrete 0.8–1.0 L of water per hour, making water intoxication likely to set in before any alcoholic intoxication. [9]
The general procedure is to write down the defining expressions for all the constants involved and then to equate concentrations. For example, suppose that one wishes to derive the pKa for removing one proton from a tribasic acid, LH 3, such as citric acid.
The "zero" refers to what the manufacturer calls "sugar-free". [6] According to nutrition labelling standards in Japan, a beverage product can be labelled as sugar-free as long as it does not exceed 0.5 g of sugar per 100 mL. [7] Strong Zero is made by freezing fruit in liquid nitrogen. Liquid nitrogen has a boiling point of −195.8 °C (− ...
