AI Thread Summary
Ionizing air purifiers, such as the Ionic Breeze, utilize charged plates and wires to attract dust particles from the air, while also converting oxygen into ozone. As dust accumulates on the plates, arcing can occur due to the increased conductivity of the dust compared to air. This arcing may lead to an increase in ozone production, as more energy becomes available to cleave oxygen molecules. However, as the dust layer thickens, it could hinder the device's ability to generate ozone by obstructing the current's contact with oxygen. The impact on dust collection efficiency remains uncertain, as it could either increase due to enhanced conductivity or decrease if the plates become too coated. Overall, the relationship between arcing, ozone production, and dust collection efficiency in ionizing air purifiers raises important considerations for their effectiveness.

Ionizing air purifiers like the Ionic Breeze advertised on TV have charged plates and charged wires running parallel to each other. Dust in the air collects on the plates, and oxygen in the air is converted to ozone. As the plates collect more and more dust, arcing begins to happen between the plates and the wires since dust is a better conductor than air.

What I want to know is how does arcing affect the usefulness of my Ionic Breeze? Voltage should be unafffected while amperage should increase. Should it collect more dust or less dust? Will it make more ozone or less ozone?
 
Chemistry news on Phys.org
Dont quote me on this,

but I would say that arcing increases the amount of ozone emitted from the device, due to more energy available in contact with air to cleave oxygen gas.

However, the plates will probably continue to attract dust, possible until there is such a thick cover that O2 is unable to contact the current, and ozone production decreases.

Just a guess...
 

Thread 'Solubility of MgSO47H2O in water'

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...

Thread 'Why does having 8 valence electrons make an element inert?'

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!!
