An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...

Many chemicals can be classified as being acidic, neutral or alkaline by using indicators. The pH scale is used to measure acidity and alkalinity. When an acid is neutralised, it forms a salt.

In a titration, sulfuric acid of concentration \(0.1 moll^{-1}\) was added from a burette into a conical flask containing \(20cm^{3}\) of sodium hydroxide solution. The average titre was \(11.2cm ...

A cotton swab is dipped into concentrated hydrochloric acid (producing hydrogen chloride gas) while a second on is dipped into concentrated aqueous ammonia (producing ammonia gas). Both cotton swabs ...

Describes acid-base physiology and discusses the diagnosis and treatment of disorders associated with metabolic acidosis and metabolic alkalosis, as well as plasma potassium disorders. Metabolic ...

Not only are these proteins assembled with different amino acid sequences, but they also are held together by different bonds and folded into a variety of three-dimensional structures. The folded ...

Within 2 minutes, precise and reliable acid number values can be obtained. The titration glass sensors for standard acid/base application in aqueous media or non-aqueous solutions are specifically ...

Hidden within the genetic code lies the "triplet code," a series of three nucleotides that determine a single amino acid. How did scientists discover and unlock this amino acid code? Once the ...

Various titration types include redox, acid/base, and precipitation titrations. Here, a self-finding inflection point method can be applied for numerous applications. The analyzer can also be used to ...
