Solubility H2O: 10 mg/mL at 20 °C, clear, colorless Form Liquid Pka 10.40, 8.26(at 25℃) Color Clear colorless to slightly yellow General Description Lithium bistrimethylsilylamide is also called lithium hexamethylsilylamide (LiHMDS). Lithium bistrimethylsilylamide can be used to prepare ...
of this reaction, I know from personal experience that it’s quite exothermic, meaning the solution will get quite hot. If the reactants are sufficiently concentrated, the reaction could explosively boil, so if you feel the insane urge to react concentrated reagents, do the addition ...
Pka 7.38(at 25℃) Form Liquid Specific Gravity 0.920 (20/4℃) Color Clear PH 10.6 (50g/l, H2O, 20℃) Explosive limit 2.1%(V) Water Solubility >500 g/L (20 ºC) N-methyl morpholine is an important fine chemical product. It is an excellent solvent, emulsifier, corrosion...
HA + H2O ⇆ A- + H3O+ where HA is the acid and A- is the conjugate base. Ka = [A-][H3O+] / [HA][H2O] This is used to calculate pKa, the logarithmic constant: PKA = – log10 Ka The larger the pKa value, the smaller the dissociation of the acid and the weaker the acid...
Which scenario is correct Scenario 1 Ph/ pKa: 6.401 i will have it will have (0 amount of) Na3C6H5O7, and (100%) Na2C6H6O7 as the sodium will disassociate, at pH /pKa 4.76, there is (Zero amount of) Na2C6HO7 and (100%) NaC6H5O7 and at A Ph/pKa of 3.138 (Zero amount...
