yula Posted September 20, 2010 Share Posted September 20, 2010 why there were two peak when i used Cr(NO3)3 as the sample for uv/vis spectrophotometry? and the graph is absorption against vawelength, how to convert the graph to absorption against concentration?

ewmon Posted September 20, 2010 Share Posted September 20, 2010 This sounds like homework. Tell us what have you done so far? Tell us what you know about Cr(NO3)3? Link to comment Share on other sites More sharing options...
mississippichem Posted September 20, 2010 Share Posted September 20, 2010 Try manipulating the equation for the Beer-Lambert law, as far as concentration goes. Getting two peaks in your spectrum? what was [math] \lambda [/math] for the two peaks? Link to comment Share on other sites More sharing options...
yula Posted September 22, 2010 Author Share Posted September 22, 2010 this is my experiment on analytical chemistry..thanks for respons,i already asked my lecturer about the graph and i had drew the first graph, and on my way for the second graph.
