In many chemical reaction, Pt is used as catalyst often. I'm wondering for what reason Pt is used in many process.

"for his studies of chemical processes on solid surfaces" i thought nobel prize was rewarded for the research which have some meaning to the chemistry. In this study i found it hard to find some meaning. what i found one was that some other techniques were developed because of doing this...

What i mean is that when doing neutralization titration, we need to measure the concentration. And i want to measure it by spectrophotometer. But when using spectrophotometer, i often need to go through dilution process. Then, while doing the dilution process in the acid solutiton, the...

when inducing that the cycloid is the least time-taking course between the two points in the two dimension, we have to use calculus of variations. Then is it possible to induce the parameter of the least time-taking course between two points in the three dimension?

When using spectrophotometer, to use Rambert-beer's law, we often go through dilution process. Then when measuring neutralization reaction and using week acid or base, then because of water's autoionizaition, i think the results have error. Is it right?

The topic in the prize is about GPCR and from what i have researched, the research is about biology. I want to know why it was rewarded to the field in chemistry.

Oh, so is there a table about the RI and concentration? i didn't know that. i think we didn't do research about the HPLC method. But i think, for measuring RI, it will measure like spectrophotometer. if not i want to know how i can research the HPLC method

We are using NaCl solution. We are just using another way to measure RI. During our research, we knew that HPLC can measure the concentration of the solution. But what we found via wiki told me that there is no linear relations between concentration of the solution and RI. So we are wondering...

i'm a student in high school and I'm having a problem figure out the relationship between RI and concentration of the solution. What i found suggest that there is no linear relation. However, HPLC does allow us to know the concentration of the solution based on RI. My question here is that how...

< Mentor Note -- two threads merged and new user reminded not to multiple-post threads at the PF >[/color] i'm experimenting about refractive index and i can't figure out the relationship between concentration of the solution and Refractive index. What i found about this is that RI is...
