Aqueous chemistry in the clouds of Venus

Droplet chemistry in the clouds of Venus may play a role in regulating the depletion of sulfur dioxide and water vapor in and above the clouds. The specific nature of this chemistry is unknown. In this talk, I present three different scenarios for aqueous chemistry in the cloud droplets:

• Hydroxide salts
• Reduced sulfites
• Iron sulfates

I will discuss the effects of these three different aqueous chemistries, some of which may be accessible via remote observation. The iron sulfate chemistry in particular provides a candidate for the unknown UV absorber.
