Why does laterite fizz when placed in water?

[Peter Wilson]

When I place laterite in plain tap water (alkaline) it's produces very tiny
bubbles and fizzes for a few moments and keeps releasing tiny bubbles for at
least a minute.

Does anyone know what this gas is?

What is your laterites pH?

What does laterite feel like when you put it on your tounge? My tounge
sticks to it with a vengence!!

Cheers from Australia,

Air.

Should be neutral.

Chalk. The stuff is utterly void of water, it's just taking water on
and tiny air bubbles inside are escaping. No worries.
