Phenolic acids consist of two subgroups: the hydroxybenzoic and hydroxycinnamic acids.Hydroxybenzoic acids include gallic, p-hydroxybenzoic, protocatechuic, vanillic and syringic acids, which in common have the C6–C1 structure. Hydroxycinnamic acids, on the other hand, are aromatic compounds with a three-carbon side chain (C6–C3), ...

Sulfonation with sulfuric acid is a special case of oleum sulfonation. Because the sulfonation reaction stops when the acid concentration in the reaction mixture drops to less than approximately 90%, sulfonation of detergent feedstocks with sulfuric acid is not normally practiced. Today sulfuric acid sulfonation is principally used for ...

10. The concentration of a monochloro acetic acid solution is 0.001 M. What are the pH and the degree of dissociation in this solution? Ka = 1.2×10-3 Monochloro acetic acid is a weak acid and we do not have enough difference in the order of magnitude so the following formula should be used: [H ] c [H ] [H ] weak acid a + + + K = ⋅ −
The titration was carried out at a pH between 7 and 10 because chromate ion is the conjugate base of the weak chromic acid (2, 3). Therefore, when the pH is lower than 7, chromate ion is protonated and the chromic acid form predominates in the solution. Consequently, in more acidic solutions the chromate ion concentration is too

Prussic Acid. Prussic acid poisoning of grazing livestock can also be a problem during and immediately after a drought, or after a freeze in the fall. Prussic acid poisoning, compared to nitrate poisoning, only occurs with sorghum family plants (i.e., johnsongrass, haygrazers, milo, grain sorghum). Since millet is not a sorghum, it will not cause

Bicarbonate of soda is alkaline and needs an acid to get it working. Yoghurt, buttermilk and cream of tartar are commonly used to do this. Baking powder is a ready mix of bicarbonate of soda and an acid. It’s inactive as long as it’s dry and starts working when it comes into contact with liquids. Once opened, raising agents have a limited

in fatty or oily solutions and not in water. This makes them difficult for the body to excrete. Fat soluble chemicals have a high affinity for fat tissues and cell membranes, which are composed of fatty acids and proteins. In these fatty tissues of the body, toxins may be stored for years, being released during times of exercise, stress or fasting.
The process for electrorefining copper is typical of those carried out in aqueous solution. The electrolyte is copper sulfate (0.7 molar) and sulfuric acid (2 molar) and the way in which the purification of the copper occurs can be seen by considering the metals likely to be found. as impurities :
