Citric acid is a triprotic acid, with pK a values, extrapolated to zero ionic strength, of 3.128, 4.761, and 6.396 at 25 °C. [21] The pK a of the hydroxyl group has been found, by means of 13 C NMR spectroscopy, to be 14.4. [22] The speciation diagram shows that solutions of citric acid are buffer solutions between about pH 2 and pH 8. In ...
Biological substances can experience leaching themselves, [2] as well as be used for leaching as part of the solvent substance to recover heavy metals. [6] Many plants experience leaching of phenolics, carbohydrates, and amino acids, and can experience as much as 30% mass loss from leaching, [5] just from sources of water such as rain, dew, mist, and fog.

Acid-base extraction utilizes the difference in solubility of a compound in its acid or base form to induce separation. [4] Typically, the desired compound is changed into its charged acid or base form, causing it to become soluble in aqueous solution and thus be extracted from the non-aqueous (organic) layer. [5] Acid-base extraction is a ...
Henarathgoda Botanical Garden, also known as Gampaha Botanical Garden, is one of the six botanical gardens in Sri Lanka. The botanical garden is situated on the Gampaha-Minuwangoda main road, approximately 450 m (1,480 ft) away from Gampaha railway station. It is about 29 km (18 mi) from Sri Lanka's commercial capital of Colombo. [2] [3]
The rhizosphere is the thin area of soil immediately surrounding the root system. It is a densely populated area in which the roots compete with invading root systems of neighboring plant species for space, water, and mineral nutrients as well as form positive and negative relationships with soil-borne microorganisms such as bacteria, fungi and insects.
Extraction in chemistry is a separation process consisting of the separation of a substance from a matrix. The distribution of a solute between two phases is an equilibrium condition described by partition theory.
[14] Growth of terrestrial plants without soil in mineral nutrient solutions was later called "solution culture" in reference to "soil culture". It quickly became a standard research and teaching technique in the 19th and 20th centuries and is still widely used in plant nutrition science.
Bioprospecting (also known as biodiversity prospecting) is the exploration of natural sources for small molecules, macromolecules and biochemical and genetic information that could be developed into commercially valuable products for the agricultural, [2] [3] aquaculture, [4] [5] bioremediation, [4] [6] cosmetics, [7] [8] nanotechnology, [4] [9] or pharmaceutical [2] [10] industries.
