Example acids and bases?
Best insight from top research papers
Acids and bases are important in various contexts. In indoor air quality, acids such as CO2, HNO3, and organic acids like formic and acetic acid, can influence the suitability of indoor environments for occupants . In enzyme chemistry, acid-base chemistry plays a crucial role in understanding reaction mechanisms and catalysis. According to the Bronsted definition, acids are substances that tend to lose a proton, while bases accept protons . In atmospheric aerosols, displacement reactions occur where strong acids like HCl and HNO3, or bases like NH3, are substituted by weaker ones, altering the aerosol composition and affecting environmental systems . In ambient temperature ionic liquids, acids and bases can range from Lewis basic to acidic, and from Bronsted acidic to superacidic . These examples demonstrate the diverse roles and characteristics of acids and bases in different fields.

What is a natural acid base indicator?5 answersA natural acid-base indicator is a substance derived from plants that changes color based on the pH of a solution. These indicators are eco-friendly, cost-effective, and easily accessible. Various plants like Hibiscus rosa-sinensis, Ipomoea batatas, Clitoria ternatea, turmeric, rose, red cabbage, and Ixora coccinea have been studied for their indicator properties. Natural indicators offer a sustainable alternative to synthetic indicators, which can be toxic and expensive. They exhibit color changes at specific pH levels, aiding in the determination of the equivalence point in acid-base titrations. The effectiveness of natural indicators has been demonstrated in various studies, showcasing their utility in analytical chemistry applications.
What is acid base ratio?5 answersThe acid-base ratio refers to the relationship between acidic and basic components in a system. In the context of medical research, the chloride:sodium (Cl-:Na+) ratio is proposed as a quick assessment of the impact of chloride and sodium on acid-base balance in critically ill patients. Additionally, a colorimetric ratio-type acid-base fluorescent probe has been developed for pH detection in the range of 6.0-8.0, showing color changes based on pH levels. Furthermore, the mole ratio in acid-base reactions is crucial for understanding the stoichiometric relationship between acids and bases, with models developed to predict acid volumes in titration processes. When diagnosing mixed acid-base disorders, the DeltaAG/DeltaHCO3- ratio is considered, although its wide range limits individual diagnostic accuracy. Arterial blood gas tests provide essential values like pH, pO2, pCO2, HCO3-, and base excess for evaluating acid-base status in clinical settings.
How to determine the acids and bases?4 answersAcids and bases can be determined using different approaches. The physiologic approach considers acids as hydrogen ion donors and bases as hydrogen ion acceptors. It assesses acid-base status by using the carbonic acid/bicarbonate buffer pair and measuring blood pH. Another approach is the physicochemical approach, which posits that the acid-base status is determined by changes in the dissociation of water driven by three independent variables: the sum of strong cation concentrations minus the sum of strong anion concentrations, the total concentration of weak acids, and Paco2. Acid-base characterization of catalysts can be done using various techniques such as Hammett's indicators, adsorption measurements, and other spectroscopic techniques. The basic concepts of acids and bases, including their definitions, strong and weak acids and bases, and equilibrium expressions, are important in solving acid-base equilibrium problems. The evaluation of acid-base status depends on accurate measurement of acid-base variables and can be done using different approaches such as the physiological approach and Stewart's approach. A general approach using potentiometric titration can be used for the quantitative determination of mixtures of mono- and poly-protic substances.
What are the theories of acid-base?5 answersThe theories of acid-base include the traditional chemistry theories, the van Oss, Chaudhury and Good acid-base theory, the theory of acids and bases developed by M.I. Usanovich, and the Lewis theory of acids and bases. The traditional chemistry theories do not take into account the quantum mechanical effects that arise from the acidic hydrogen shuttling potential and its dependence on the acid base distance. The van Oss, Chaudhury and Good acid-base theory focuses on determining and comparing the acid-base behavior of materials using various measurement techniques. The theory developed by M.I. Usanovich introduces the concept of "hard" and "soft" acids and bases (HSAB) and their interaction preferences. The Lewis theory of acids and bases is regarded as the most versatile and rigorous concept, explaining acid/base behavior and polar covalent reactions.
