Titration is used in many laboratories using colored indicators to show when an acidic solution becomes basic by changing color. The amount of base needed to neutralize the acid is known as the endpoint. Another way to determine the endpoint without doing a physical lab demonstration is to ...
How is a calibration plot for an ISE prepared? Why is it needed? Potentiometric Cell It consists of two electrodes immersed in a solution that used to determine the electric potential generated in the cell. The two electrodes act as cathode and anode. ...

II. Pipette exactly 25 ml of the approximately 0.05 M H3PO4 into a 250 ml beaker, and dilute with water to 100 ml. Set up the beaker and burette containing sodium hydroxide solution as in the previous titration, and measure the pH of the solut...
formation for each sample. A plot of velocity (V) vs. concentration ([S]) produces a curve that climbs rapidly and levels off at the maximum velocity, which is the point at which the enzyme is working as fast as it can. This is called a saturation plot or Michaelis-Menten plot. ...
In order to estimate the binding strength between AlbAS and albicidin, we monitored characteristic signals in a well-resolved reporter region of the 1H-15N HSQC spectrum during a titration series (Supplementary Figure 8A). The simultaneous observation of signals arising from both AlbAS and its al...
2.2. Pain titration Upon arrival, each participant met three co-players (i.e., confederates). All the three confederates were university students of the same sex as the participant to avoid the possibility that the perceived age and sex of the co-players influence the participant's respo...
The typical DAT pattern in CAD is a strongly positive test for C3 (usually C3d) only, but in up to 20% of patients, DAT is weakly positive for IgG as well.1, 10 Because DAT can be positive for C3 only, even in IgM-mediated warm AIHA,35, 36 CA titration is mandatory for ...
AI has achieved sentience. AI is already about a thousand times smarter than any human being on the planet. AI has emotions. AI is absolutely not “predicting the next word.” AI is an existential threat. AI lies a lot, but more importantly, it’s programmed to lie—...
How does Beer's Law allow the determination of the concentration of Allura Red AC in the beverage or food sample? (Be sure to specifically define Beer's Law.) How to draw a curve with the Beer's law? Why is the y-intercept of a Beer's Law plot supposed to be zero? Beer's Law...
