Indicators are used to determine the equivalence point in acid – base titrations (neutralization titrations). They exhibit sharp color change with respect to change in pH. Popularly used indicators for neutralization titrations are synthetic chemicals. They are found to have hazardous effects in human body. The highly colored pigments obtained from plants are found to exhibit color changes with variation in pH. A study was done to check the indicator action of aqueous extract of flower pigments and compared with that of already existing synthetic indicators. Extraction was done using hot

We have used stopped-flow kinetic studies to conduct an investigation into the acid neutralization reaction between overbased detergent additives and aqueous acid dispersed as w/o microemulsion droplets. Water-soluble pH indicators have been used to monitor the change in pH during the reaction. The acid neutralization rate was found to be dependent on the concentration of overbased additive, the temperature of the system, and the hydrocarbon chain length of the solvent. The systems are of importance in relation to the mechanism of acid neutralization by engine lubricants.Key words: overbased d

Indicators used in acid-base titration show well marked changes of colour in certain intervals of pH. Most of these indicators are organic dyes and are of synthetic origin. Today synthetic indicators are the choice of neutralization titrations. But due to environmental pollution, availability and cost, the search for natural compounds as an acid-base indicator was started. The present work highlights the use of the ethanolic extract of the corolla of Roselle (Hibiscus sabdariffa) as a pH indicator in strong acid-strong base, strong acid weak base, weak acid strong base and weak acid-weak base

Immunotherapy implies the use of an immune-based therapy to treat infection.

While agents such as corticosteroids, thalidomide, and vitamin D have profound effects on immune function and a well-established role in the treatment of some infections (e.g. corticosteroids in tuberculous and pneumococcal meningitis), in this revi

Abstract In the course of an ongoing investigation into the phenomenon of naphthenic acid corrosion, a new test method has evolved and is currently being further developed to substitute the total acid number (TAN or neutralization number) as an indicator for naphthenic acid corrosion potential. It can also be used to complement conventional autoclave corrosion tests in high temperature environments, which are based on weight loss of steel coupons. In this new method an oil sample reacts with pure iron powder within an autoclave heated to the testing temperature. The result is based on the amou

A number of mechanisms have been proposed to explain rebound, and to some extent each may contribute to the phenomena. As yet no reliable, predictable method has been demonstrated for measuring, reproducing or quantifying "heparin rebound".We have demonstrated and measured the appearance of heparin anticoagulant activity following neutralization with prota

Mine water is one of the biggest challenges facing the global mining industry. This water is primarily produced by the oxidation of sulfide minerals when exposed to air, water, and microbial activity in active or abandoned mines containing polymetallic sulfide ores or coal mines. It is characterized by high acidity, with a pH value usually below 4, which usually indicates high concentrations of sulfates and dissolved metal ions. There are two different treatment strategies: removing toxic metals and reducing the acidity of mine water. Processes for neutralization of acid mine waters with lime

Investigation was performed in the water, at different pH values (0-14). Acid-base species, which are represented in diverse molar fraction (f) at different pH values, contribute to a comprehensive examination of antiradical capacity. An overall rate constant (koverall) of the favorable reaction pathways (HAT and RAF) of 2.07×102 M-1s-1 at physiological pH indicates a moderate ability to neutralization HOO• radicals. A

Non-destructive inspection of steel plates for "hard spots" (HS) is a modern requirement imposed by most energy companies on steel plate manufacturers. The most suitable testing method involves the application of eddy current (EC) probes, specifically pulse eddy current (PEC) probes, which are generally sensitive to areas with abnormal hardness. However, a significant challenge in the industrial application of EC or PEC probes lies in the inevitable residual magnetization of plates and other rolled materials.
