The Henderson–Hasselbalch equation can be used to model these equilibria. It is important to maintain this pH of 7.4 to ensure enzymes are able to work optimally. [10] Life threatening Acidosis (a low blood pH resulting in nausea, headaches, and even coma, and convulsions) is due to a lack of functioning of enzymes at a low pH. [10]
Concentrated sulfuric acid with a specific gravity of 1.8 has a Twaddell scale measurement of 160 (as per the linear relationship between readings and sp. gravity). The Twaddell scale is only used for liquids with specific gravity greater than that of water. The scale was used in the British dye and bleach manufacturing industries.
The unified absolute pH scale is based on the absolute chemical potential of the proton, as defined by the Lewis acid–base theory. This scale is applicable to liquids, gases, and even solids. [23] The advantages of the unified absolute pH scale include consistency, accuracy, and applicability to a wide range of sample types.
Using soap helps dissolve many water-insoluble substances, like fats and oils, making them washable with water. In most cases, hard soaps or products based on them are used for handwashing because they exhibit an alkaline ( pH value above 7) nature and can irritate the skin when in contact with mucous membranes.
Handmade soap makers who aim for bar soap use sodium hydroxide (NaOH), commonly known as lye, rather than KOH (caustic potash) which produces soft paste, gel or liquid soaps. In order to calculate the lye amount needed to make bar soap, KOH values of SV can be converted to NaOH values by dividing KOH values by the ratio of the molecular weights ...
