pH can be measured using indicators, which change color depending on the pH of the solution they are in. By comparing the color of a test solution to a standard color chart, the pH can be estimated to the nearest whole number. For more precise measurements, the color can be measured using a colorimeter or spectrophotometer.
Photosynthesis ( / ˌfoʊtəˈsɪnθəsɪs / FOH-tə-SINTH-ə-sis) [ 1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.
Soil pH is a key characteristic that can be used to make informative analysis both qualitative and quantitatively regarding soil characteristics. [ 1] pH is defined as the negative logarithm (base 10) of the activity of hydronium ions ( H+. or, more precisely, H. 3O+. aq) in a solution.
Phytic acid is a six-fold dihydrogenphosphate ester of inositol (specifically, of the myo isomer ), also called inositol hexaphosphate, inositol hexakisphosphate ( IP6) or inositol polyphosphate. At physiological pH, the phosphates are partially ionized, resulting in the phytate anion . The ( myo) phytate anion is a colorless species that has ...
Phosphorus is an essential mineral for humans listed in the Dietary Reference Intake (DRI). Food-grade phosphoric acid (additive E338 [ 105]) is used to acidify foods and beverages such as various colas and jams, providing a tangy or sour taste. The phosphoric acid also serves as a preservative. [ 106]
Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite. This is in accordance with Justus von ...
Intracellular pH ( pHi) is the measure of the acidity or basicity (i.e., pH) of intracellular fluid. The pH i plays a critical role in membrane transport and other intracellular processes. In an environment with the improper pH i, biological cells may have compromised function. [ 1][ 2] Therefore, pH i is closely regulated in order to ensure ...
Bicarbonate indicator. A hydrogencarbonate indicator (hydrogencarbonate indicator) is a type of pH indicator that is sensitive enough to show a color change as the concentration of carbon dioxide gas in an aqueous solution increases. The indicator is used in photosynthesis and respiration experiments to find out whether carbon dioxide is being ...
