Spectrophotometry is an invaluable tool in chemistry and biology. The basic idea is simple: different substances absorb light/electromagnetic radiation better at some wavelengths than at others. That's why some materials are transparent while others are colored, for example. When you shine light of ...

Molarityis a unit ofconcentration, measuring the number of moles of a solute per liter of solution. The strategy for solving molarity problems is fairly simple. This outlines a straightforward method to calculate the molarity of a solution. The key tocalculating molarityis to remember theunits of...
How to calculate concentration of NaOH in titration? Acid-Base Titration: Titration is an analytical technique used in chemistry that allows for the determination of an unknown quantity or a concentration of an analyte using a known concentration of a titrant. A titrant is a solution that reacts...
I have obtained the standard deviation at each concentration, how can I calculate the standard deviation of the calibration line (not at each concentration)? standard-deviation chemistry Share Cite Follow edited Dec 31, 2016 at 0:40 asked Dec 30, 2016 at 19:32 Nocturnal 11911 ...
I am known to be occasionally wrong. Re: How to calculate what percentage of Ca2+ remains unprecipitated? «Reply #3 on:March 03, 2012, 04:39:04 PM » You have not expressed what is happening as an equation. During precipitation concentration of both Ca2+and SO42-goes down by x....
The rate law can be determined by themethod of initial rates. In this method, the experiment is performed multiple times, only changing the concentration of one reactant for each run while keeping other variables constant. The rate of the reaction is measured for each run to determine the ord...
On a calibration curve for Abs vs Concentration, explain how to determine the sensitivity or how to calculate it. Calibration Curves Calibration curves are used in chemistry and other scientific disciplines often. A calibration is a pot of the concentrati...
Calculate appropriate v/v dilution using the formula C1V1 = C2V2 where C represents the concentration of the solute, and V represents volume in milliliters or ml. An example would be combining 95 percent ethanol with water to mix 100 ml of 70 percent ethanol. The calculation is 95% X V...
