Molar mass: 209.26 g·mol −1 ... Sigma Aldrich Buffer Calculator - Useful tool to calculate weight, volume, or concentration from molecular weight.
It has a useful pH range of 6.5-7.9 in the physiological range, making it useful for cell culture work. It has a pKa of 6.9 with ΔpKa/°C of -0.015 and a solubility in water at 0°C of 0.75 M. MOPSO has been used as a buffer component for: [4] Copper analysis via:
The relative concentration of undissociated acid is shown in blue, and of its conjugate base in red. The pH changes relatively slowly in the buffer region, pH = pK a ± 1, centered at pH = 4.7, where [HA] = [A −]. The hydrogen ion concentration decreases by less than the amount expected because most of the added hydroxide ion is consumed in ...
The Henderson–Hasselbalch equation can be used to model these equilibria. It is important to maintain this pH of 7.4 to ensure enzymes are able to work optimally. [10] Life threatening Acidosis (a low blood pH resulting in nausea, headaches, and even coma, and convulsions) is due to a lack of functioning of enzymes at a low pH. [10]
Molar mass: 221.32 g/mol Melting point ... Its useful pH range is 9.7-11.1. See also. CHES; Good's buffers § List of Good's buffers ... Toggle the table of contents.
Conversely, when pH = pK a, the concentration of HA is equal to the concentration of A −. The buffer region extends over the approximate range pK a ± 2. Buffering is weak outside the range pK a ± 1. At pH ≤ pK a − 2 the substance is said to be fully protonated and at pH ≥ pK a + 2 it is fully dissociated (deprotonated).
Solution structures are either solvated monomers or dimers (or mixtures thereof) with this depending on the coordinating power, concentration, and temperature of the solvent. [3] In general, weakly coordinating solvents such as toluene and N,N-dimethylethylamine give dimers, where as THF and diglyme gave monomers at high dilution. [ 3 ]
Molar concentration or molarity is most commonly expressed in units of moles of solute per litre of solution. [1] For use in broader applications, it is defined as amount of substance of solute per unit volume of solution, or per unit volume available to the species, represented by lowercase c {\displaystyle c} : [ 2 ]
