Dear geoff,
I wanted to send a design lab done by a student for your feedback.This is primarily done to investigate the trend in change in concentration of FeSCN+2 and absorption of light - using a colorimeter and the beer's law.Here he has algebraically derived the Kc value using Lambert - beer's law. Please let me know if I can send it to you,,my email id would be

Hi Anuradha, I hope you will understand if I say that I cannot really offer to look at student's work from another school. It might give that student/school an unfair advantage and also if it became common practice then I might get inundated with requests. The investigations sounds as if it should be fine for a design experiment so as long as your student has followed what is required there is no reason why he/she cannot do well.
