Citric acid sold in a dry powdered form is commonly sold in markets and groceries as "sour salt", due to its physical resemblance to table salt. It has use in culinary applications, as an alternative to vinegar or lemon juice, where a pure acid is needed. Citric acid can be used in food coloring to balance the pH level of a normally basic dye.
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.
Lemon juice and rind are used in a wide variety of foods and drinks, the juice for its sour taste, from its content of 5–6% citric acid. [28] The whole lemon is used to make marmalade, [29] lemon curd [30] and lemon liqueurs such as Limoncello. [31] Lemon slices and lemon rind are used as a garnish for food and drinks.
Most marinades are comprised of three parts: oil, spices and acid. The oil adds juiciness to the meat and the spices add flavor, but neither of those would have any affect on the meat without acid ...

Paper form: It is a strip of coloured paper which changes colour to red if the solution is acidic and to blue, if the solution is basic. The strip can be placed directly onto a surface of a wet substance or a few drops of the solution can be dropped onto the universal indicator using dropping equipment.
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 ...
The carpels are juicy; they contain a high quantity of citric acid, which with other organic acids including ascorbic acid (vitamin C) give them their characteristic sharp taste. [30] Citrus fruits are diverse in size and shape, as well as in color and flavor, reflecting their biochemistry; [ 31 ] [ 32 ] for instance, grapefruit is made bitter ...
