Chalk (used for writing on black board) contains Calcium carbonate so HCl decomposes the carbonate with bubbles of carbon dioxide gas.
CaCO3 + 2HCl ------> CaCl2 + CO2 + H2O

Does hydrochloric acid have a more dramatic effect on palladium or platinum?
no
What is the effect of hydrochloric acid on the enzyme activity?
Denature enzyme activity
What happens when water and chalk mix?
When a drop of dilute hydrochloric acid is placed on a piece of Chalk, the acid reacts with the calcite and forms bubbles of carbon dioxide. This "fizz" reaction is so characteristic of limestone than many geologists carry a small bottle of dilute hydrochloric acid into the field for a rapid and easy identification of limestone. During the reaction, the bubbles of carbon dioxide rise, then turn a brownish color, and then decrease in size. This is weird because the hydrochloric acid starts out as a white fizz.
Why the solubility of salicylic acid in water change when hydrochloric acid is added?
Because of the common ion effect.

What will be the effect if you heat the Hydrocloric acid exceeding 66 degree celsius?
When it is headed, hydrochloric acid will cause hydrochloric acid fumes.Ê If the substance is heated, based on metals that corroded to create the acid, an explosion could be caused.
