Introduction: Simple Strong Acid and Base Titration Introduction A titration is a process that allows the equilibrium ratios, or equivalent amounts, of chemicals to be observed through a change in color. The characteristic indicator that a solution has reached equilibrium is a color change which is...

filters, and titers were determined using Lenti-Xquantitative real-time polymerase chain reaction (RT-PCR) titration kit (CloneTech). The transduced cells were then transplanted into the tail vein of 3–4-week-old C57BL/6 J mice by intravenous injection which had been preconditioned with 25...
Combined with the amount of the final titration solution, the acid number of the sample was calculated. The testing equipment used was the Mettler G20S automatic titrator (METTLER TOLEDO, Zurich, Switzerland). According to the standard measurement method, the acid number measurement results for ...
(0.001 g), and after being killed at 105 °C for 30 min, the stem was dried in an oven at 80 °C to a constant amount to determine the dry mass, and the moisture content was calculated. The titratable acid content was detected by the acid–base titration method. Sugar (soluble ...

, where O2is consumed, producing anoxic conditions. The major function of the organic layer is reduction of all Fe to Fe2+, which prevents coating of the underlying limestone with ferric hydroxide. Acid neutralization occurs in the organic layer by sulfate reduction and in the limestone base....
The actual aldehyde content of A-HA was determined by hydroxylamine hydrochloride titration method, which revealed an extent of oxidation of 48.9%. The mechanism of gelation is via Schiff base reaction between amino of NOCC and aldehyde groups of A-HA. Formation of amide bond cross-linked NOCC ...
