A strong acid will react with a weak base to form an acidic (pH < 7) solution. A weak acid will react with a strong base to form a basic (pH > 7) solution. These indicators are essential tools in chemistry and biology, aiding in the determination of a solution's acidity or alkalinity through the observation of colour transitions. [ 10 ]
In chemistry, titratable acid generally refers to any acid that can lose one or more protons in an acid–base reaction. The term is used slightly differently in other fields. For example, in renal physiology, titratable acid is a term to describe acids such as phosphoric acid , sulfuric acid which are involved in renal physiology .
Cranberry juice is an acidic drink with a pH of about 2.6. [9] Some cranberry juice products contain large amounts of sugar used in manufacturing to make the drink more palatable, but their consumption may increase the risk of hyperglycemia and reduced control of blood glucose in people with diabetes or glucose intolerance.
Titration curves corresponding to weak bases and strong acids are similarly behaved, with the solution being acidic at the equivalence point and indicators such as methyl orange and bromothymol blue being most appropriate. Titrations between a weak acid and a weak base have titration curves which are very irregular.
A pH indicator is a halochromic chemical compound added in small amounts to a solution so the pH (acidity or basicity) of the solution can be determined visually or spectroscopically by changes in absorption and/or emission properties. [1] Hence, a pH indicator is a chemical detector for hydronium ions (H 3 O +) or hydrogen ions (H +) in the ...

Other measurements taken of apple varieties towards use in cider classification include pH, polyphenol composition, yeast assimilable nitrogen (YAN), [8] and soluble solid concentration (ºBrix). [18] The sharpness of an apple is affected by pH and titratable acidity. Most cultivars must reach pH levels of around 3.3 to 3.8 to aid in the ...
For fruit juices, 1.0 degree Brix is denoted as 1.0% sugar by mass. This usually correlates well with perceived sweetness. Brix measurements are also used in the dairy industry to measure the quality of colostrum given to newborn calves, goats, and sheep. [8] Modern optical Brix meters are divided into two categories.
