How is laze formed by lava mixing with sea water?

Thank you for the great answers everybody.

The high-temperature steam produced by the lava entering the ocean hydrolizes the various salts present in seawater, primarily chloride salts.  This results in hydrogen from the steam combining with chloride ions, producing significant quantities of hydrogen chloride.  As the steam recondenses it picks up this HCl to form hydrochloric acid droplets.
