>*What kind of data would be interesting to monitor in general reactions?

Spectral absorption. For example, in a colorimetric reaction (turns from, say, blue to green) you would change absorption at specific wavelengths. In a pH-dependent reaction, you could use an indicator, and translate that pH change into a color change, and in turn that color change into pitch.

Similarly, outside the visible spectrum, there are reactions that would express changes in the ultraviolet spectrum, as well as near infrared. The near infrared spectrophotometer (NIR) has a number of interferences, including water and carbon dioxide. Similarly, all these reactions have limitations, depending upon the solvent used, and the type of container (different plastics and glass will absorb at different wavelengths, 'obscuring' part of your observations).

You could also look at the concentration of a reactant, versus that of a product. So, for example, look at the concentration of hydrogen peroxide as you drop in a tiny bit of catalase. Not sure what sensors are out there for hydrogen peroxide, maybe somebody makes one. Ditto with ion specific electrodes (ISE), where you could put into motion a precipitation reaction, and examine the concentration of an ion that ends up as part of an insoluble precipitate.

"Clock" reactions would be particularly interesting if you could figure out a way to look at those. Many of these are fussy, and some are intermittent at best.

You could look at delta T in endothermic or exothermic reactions.

You could monitor light production from various photochemical reactions.

You could look at the forward progress of various reactions in which there is a limiting reagent. For example, oxidation in an atmosphere where the oxidizer (typically the oxygen found in air, but not always) is limited. Aluminum would be interesting for that- see aluminum-air battery.

You could look at redox potential; the addition of a reducing agent (sodium thiosulfate) to a solution of sodium hypochlorite (bleach).

All sorts of stuff.

Hi Everyone,

I need a chemist/biologist's help for my project.

To analyze the state of a reaction, chemists most often use their sense of vision and smell. What if each reaction could have a distinct sound/melody such that chemists would associate a sound to reactions? This would may allow them to grasp key characteristics from it such as:
- When is the reaction finished.
- What is the most reactive phase of the reaction.
- Did anything go wrong during the reaction.

What if the music generated by the reactions actually sounded good (some artists might like this one...)?

I plan to make a simple electronic circuit with a microcontroller connected to a speaker and sensors. The sensors would pickup specific data about the reaction (temperature, IR frequency emitted, color, transparency, disruption of magnetic field...) and feed the information to the controller. The controller would process the data and create sounds per a predetermined musical scheme dependent on the data (e.g. map the IR spectrum to the audible frequency spectrum).

I am an electrical engineer, so I am not a specialist in chemistry.
My issue: 
*What kind of data would be interesting to monitor in general reactions?

Feel free to tell me what you think about this mini-project and give me diverse suggestions!!!

I found a similar project online. You can read more about it in here:
