Naturally speaking, the rate at which limestone dissolves depends on the amount of rainfall and the concentration of carbon dioxide in the water. Chemical weathering is the process that breaks down rock through chemical changes. The most common agents of chemical weathering include water, oxygen, carbon dioxide, and living organisms. Chemical weathering creates holes or soft spots in rock, so the rock breaks apart more easily. Chemical and mechanical weathering often goes hand in hand; mechanical weathering breaks rock into pieces, exposing more surface area to chemical weathering. It someone wants to dissolve a rock manually, Hydrofluoric acid is the answer.

Carbonation
Chemical weathering is a process where rock is dissolved by an acid, typically carbonic acid derived from carbon dioxide in the atmosphere.
Some limestones are made by precipitation of dissolved calcium carbonate. Some cherts are formed from dissolved silicates in thermal springs and evaporite minerals, such as gypsum and rock salt (halite) are formed by evaporation of water from solutions of dissolved minerals.

The bubbles remain inside the rock once the rock has solidified.

Rock salt is formed from the evaporation of saturated solutions that are composed primarily of dissolved halite. In this case, there is no true sediment, only the solution containing the dissolved mineral that was originally present in weathered and eroded rock.
