Some indicators can't identify acids or bases, but can only tell you the approximate pH of an acid or a base. For example, methyl orange only works at an acidic pH. It would be the same color above a certain pH (acidic) and also at neutral and alkaline values....

is measured on the pH scale, which ranges from 0 to 14. The lower the pH number is, the more hydrogen ions that are being released. Water has a pH of 7, which is neutral on the pH scale. Allacidshave a pH lower than 7. A pH greater than 7 indicates analkali, or base. ...
Example A: pH = 7.2, PCO2= 60 mmHg (8 kPa), SBE = 0 mEq/L Overall change is acid. Respiratory change is also acid – therefore contributing to the acidosis. SBE is normal – no metabolic compensation. Therefore, pure respiratory acidosis. ...
(0.25moll−1NaOH) using a triple-pulse waveform withE1,E2, andE3at 0.50, −0.89, and 0.70V, respectively. Due to the basic conditions required for the detection ofamino acids, a base-stable anion-exchange column must be employed. Detection limits of 50pmol have been obtained for...
two databases in a 2PC commit will have the availability of the product of the availability of each database. For example, if we assume each database has 99.9 percent availability, then the availability of the transaction becomes 99.8 percent, or an additional downtime of 43 minutes per month...
acid–baseequilibriain the cell, or in the organism as a whole, and the acidity or alkalinity of the soil and water are of great importance for the plants or animals living in them. Both the ideas and the terminology of acid–base chemistry have permeated daily life, and the termsaltis ...
Acid–base equilibria Certain general principles apply to any solvent with both acidic and basic properties—for example, water, alcohols, ammonia, amines, and acetic acid. Denoting the solvent molecule by SH, proton transfer can give rise to the ions SH2+ and S−, sometimes called lyonium ...
Acid-base balance for all levels with interactive pages for pH, Henderson Equation, Sea-Level Diagram and High-Altitude Diagram.
maintainingopens in new tabACID complianceis extremely costly (for example, the overhead of 2 Phased Commit/2PC protocols) when a transaction spans possibly dozens of instances. As a result, NoSQL databases that rely heavily on horizontal scaling for performance often use the BASE transaction model...
