How Can I Accurately Measure the Rate of Reaction in Homogeneous Catalysis?

AI Thread Summary
In the discussion on measuring reaction rates in homogeneous catalysis, two primary methods are considered: measuring pH changes and monitoring the consumption or generation of optically active compounds. Measuring pH changes is highlighted as the simpler approach, utilizing a pH meter for direct measurement. However, the accuracy of measuring optical properties is acknowledged, despite potential complications such as maintaining a constant temperature during the reaction. The feasibility of each method largely depends on the specific reaction and catalyst being studied. If the reaction does not produce significant pH changes, alternative methods may need to be explored. Overall, the choice of method should align with the characteristics of the reaction and the catalyst involved.

I'm studying homogeneous catalysis and reaction kinetics, and I want to conduct an experiment that measure the rate of reaction by either:

1. a pH change​
or
2. consumption or generation of a compound bearing optical properties.​

Which one is more feasible? Hopefully you'll suggest a nice reaction.

What other ways can I experimentally measure the rate of reaction accurately (besides pressure change for 2H2O2 -> 2H2O + O2)?

For option 1) simply measure the pH change using a pH meter, this would probably be the simplest approach.
 
I think measuring the optical properties will be more accurate, but there will certainly be complications involved in keeping the reaction at constant temperature, etc.

so measuring pH change will be more simple. Is there a reaction that comes to your mind?

Thnx in advance for helping me :)
 
not exactly, I though that perhaps this was specified in your assignment. If the reaction does not involve significant trend in pH change, then obviously you'll have to consider another method. It all depends on which catalyst you have in mind or were assigned.
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
