When pH>pKa, there will be more of deprotonated form. This can be seen through Henderson-Hasselbach Eq. pH=pKa+log(A-/HA). 2007-11-01 · Pi is the ratio of the circumference of a circle to its diameter. Its decimal approximation starts 3.14159 Pi (π) is the 16th letter of the Greek alphabet and was chosen from the first letter of the Greek word for perimeter ("περίμετρος") They are not the same thing other than their Greek letters sound similar.

Isoelectric focusing (IEF), also known as electrofocusing, is a technique for separating different molecules by differences in their isoelectric point (pI). It is a type of zone electrophoresis usually performed on proteins in a gel that takes advantage of the fact that overall charge on the molecule of interest is a function of the pH of its surroundings. 2016-05-13 · Whether you want to monitor a pool, aquarium or some other body of water, connecting a pH sensor to a Raspberry Pi can be achieved relatively easily.

We often hear that certain substances are acidic or basic in nature. But how does one find out whether the substance is acidic, basic or neutral?

99. what my friend told me was that I have to look at the pI value and see where the amino acid has an overall charge of 0. then i'm supposed to see where the pKa values were and where the pH is.

The isoelectric point (pI) is the point at which the net charge on a molecule is zero. pI is most commonly examined for proteins.

An salt is considered a strong ion exchanger if it remains almost fully ionized over a wide pH range, and it is considered a weak ion exchanger if it is ionized over a narrow pH range.
