pH - is a measurement of how acidic or basic a water-based solution is. The measure of acidity and alkalinity of a solution is based on a number scale where the value of 7 represents neutrality and lower numbers indicate the increases of acidity and higher numbers the increases of alkalinity.

pKa- The Ka value in chemistry is known as the acid-dissociation constant and is a measure of the ionic dissociation of the H+ proton in an acid solution, which shows the strength of that acid where greater dissociation occurs more acidic.

pl- The isoelectric point, is the pH at which a particular molecule carries no net electrical charge or is electrically neutral in the statistical mean.
The net charge on the molecule is affected by the pH of its surrounding environment and can become more positively or negatively charged due to the gain or loss, respectively, of protons (H+).

Likewise, at a solution pH that is below the pI, the surface of the protein is predominantly positively charged, and repulsion between proteins occurs. However, at the pI, the negative and positive charges are balanced, reducing repulsive electrostatic forces, and the attraction forces predominate, causing aggregation and precipitation. The pI of most proteins is in the pH range of 4 to 7. Mineral acids, such as hydrochloric and sulfuric acids, are used as precipitants

1) In chemistry, pH is a logarithmic scale used to specify the acidity or basicity of an aqueous solution.

2) pKa is defined as the negative log10 of the dissociation constant of an acid, its Ka. Therefore, the pKa is a quantitative measure of how easily or how readily the acid gives up its proton [H⁺] in solution and thus a measure of the "strength" of the acid. Strong acids have a small pKa, weak acids have a larger pKa.

3)pI ( isoelectric point) is the pH at which a particular molecule carries no net electrical charge or is electrically neutral in the statistical mean. The standard nomenclature to represent the isoelectric point is pH(I), although pI is also commonly seen, and is used in this article for brevity.

pH is a measure of the hydorgen ion concentration of a solution used to specify the acidity or basicity of an aqueous solution.

pKa is the negative base-10 logarithm of the acid dissociation constant (Ka) of a solution.The reason pKa is used is because it describes acid dissociation using small decimal numbers.

pl is the isoelectronic point or isoionic point which is the pH at which the amino acid does not migrate in an electric field.

pH = -log[H+]
pH is a measure of hydrogen ion concentration, a measure of the acidity or alkalinity of a solution. The pH scale usually ranges from 0 to 14. Aqueous solutions at 25°C with a pH less than 7 are acidic, while those with a pH greater than 7 are basic or alkaline. A pH level of 7.0 at 25°C is defined as "neutral" because the concentration of H3O+ equals the concentration of OH− in pure water. 

pKa = -logKa
The pKa measures the "strength" of a Bronsted acid.  A strong Bronsted acid is a compound that gives up its proton very easily.
A weak Bronsted acid is one that gives up its proton with more difficulty.

pI—called the “isoelectric point,” this is the pH at which a molecule has a net neutral charge. Also, the pI is the point where the protein is least soluble in water (because it has no net charge); this can help determine which proteins are more soluble than others.
