Hurricane Lane

[ScienceNostalgia101]

Wasn't sure whether to take this to the physics or chemistry forum, as it involves both, but for now I'll put it here.

Quote

• Hurricane Lane will create "whiteout conditions," life-threatening flash floods and landslides as it hits the Kilauea volcano.
• When it hits the lava, the rain creates steam that's loaded with particles and toxic gases, such as hydrochloric acid.
• In 2013, eruptions from Kilauea increased the intensity of thunderstorms and lightning around Tropical Storm Flossie.

Why would lava contain hydrochloric acid? Wouldn't hydrogen chloride be more likely to come out of solution at the higher temperatures of lava than at the lower temperatures of rain-cooled lava?

 

Or does it dissolve-without-dissociating in lava, then react with rainwater to form hydrochloric acid?

 

I was expecting this to be an "at least we won't have to worry about the lava once the water freezes it, or about the ash once the rainwater dissolves it" situation. So much for that...
