Absorbance (A) is the flip-side of transmittance and states how much of the light the sample absorbed. It is also referred to as “optical density.” Absorbance is calculated as a logarithmic function of T:A = log10 (1/T) = log10 (Io/I). What is KF in Freundlich? The units of ...
What is the advantage of reading the absorbance rather than the percent transmittance on a spectrophotometer? What is meant by the "endpoint" of a titration? What color change would get when one drop of BTB to CH_3COONa? What do we mean by the equivalence point in a titration?
a当人们说“某件事就在街角了”意味着距离很近,但是“另一个”街角彷彿预示一个未知的距离和疑问。 When the people said “some matter on had meant in the corner” is away from very near, but “another” the corner indicates an unknown distance and the question as if.[translate] ...
What is LSPR and how is it different from traditional SPR? Traditional SPR uses a continuous gold film, whileLSPR is created through metal nanoparticles, usually silver and gold. A powerful resonance absorbance peak is produced in the visible range of light by LSPR. ...
Explain why knowing the limiting and excess reagents at each point on the titration curve is important. How was UV-visible spectrophotometer used to relate the absorbance to the concentration of the aspirin? What is the purpose of the blank solution in the volumetric analysis method? Why ...

aThe first-order plots of ln(A - A∞) vs time (A and A∞are denoted to the absorbance at the reaction time and the final absorbance, respectively) were linear until three or more half-lives,with the correlation coefficient F > 0.999. 正在翻译,请等待... ...
Which is better: Pampers Swaddlers or Baby Dry? Check out their similarities & differences so you can choose the right diaper for your baby.
What is the mechanism of Na+ reabsorption(with the exception of the descending limb of the loop of Henle) and how is the reabsorption of other solutes coupled to it?
Why is it important to use the same cuvette throughout an experiment when measuring the absorbance of a solution? How would each of the folowing affect the accuracy of the calculated neutralizing power of the antacid (too high, too l...
