In and of themselves, pH indicators are usually weak acids or weak bases. The general reaction scheme of acidic pH indicators in aqueous solutions can be formulated as: HInd (aq) + H 2 O (l) ⇌ H 3 O + (aq) + Ind − (aq) where, "HInd" is the acidic form and "Ind −" is the conjugate base of the indicator. Vice versa for basic pH indicators ...
In the United States, Pepsi is made with carbonated water, high fructose corn syrup, caramel color, sugar, phosphoric acid, caffeine, citric acid, and natural flavors. [79] A can of Pepsi (12 fl ounces) has 41 grams of carbohydrates (all from sugars), 30 mg of sodium , 0 grams of fat , 0 grams of protein , 38 mg of caffeine, and 150 calories .
Reaction of sodium bicarbonate and an acid produces a salt and carbonic acid, which readily decomposes to carbon dioxide and water: [79] NaHCO 3 + HCl → NaCl + H 2 O+CO 2 H 2 CO 3 → H 2 O + CO 2 (g) Sodium bicarbonate reacts with acetic acid (found in vinegar), producing sodium acetate, water, and carbon dioxide: NaHCO 3 + CH 3 COOH → CH ...
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. In contrast, alkalosis is characterized by excessively high blood pH. Blood pH is usually slightly basic, with a pH of 7.365, referred to as physiological pH in biology and medicine.
In chemistry, an acid–base reaction is a chemical reaction that occurs between an acid and a base.It can be used to determine pH via titration.Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems; these are called the acid–base theories, for example, Brønsted–Lowry acid–base theory.
Pepsi might be Coke's slightly less popular cousin but it still manages to pack more sugar. Specifically, it has 2 more grams of sugar than Coke. Specifically, it has 2 more grams of sugar than Coke.
The hydrochloric acid produced by the Leblanc process was a major source of air pollution, and the calcium sulfide byproduct also presented waste disposal issues. However, it remained the major production method for sodium carbonate until the late 1880s.
It is a "totally new product" which resembles standard Pepsi but reportedly tastes less "acidic". [ 1 ] [ 2 ] Crystal Pepsi was launched in 1992 with a huge marketing campaign and to great success, capturing a 1% soft drink market share worth US$474 million in its first year.
