Yes, it is true.
This is chemical weathering. Carbonic acid (and often sulphuric acid from SO2) destroy CaCO3 (limestone) through chemical attack.Carbonic acid is formed by reaction of H2O and CO2 to create H2CO3.
Diffrent weathering
Some characteristics of chemical weathering include the breaking down of rocks and minerals through chemical reactions, such as dissolution, oxidation, and hydrolysis. It often results in the formation of new minerals and changes in the composition and structure of the original rock. Chemical weathering is influenced by factors such as temperature, moisture, and the presence of certain substances or organisms.
Chemical and biological weathering are different because: a) biological weathering - this means that if a seed of a plant gets coincidentally deposited in a crack in a rock, if it is humid enough, the see will grow. it's roots will spread out and eventually break the rock. b) chemical weathering - this means that chemicals in rain/acid rain weathers away the rock.
Chemical weathering can also be caused by the acids produced by some plants. The simple plant, lichen, is an example. As lichens grown on the surface of rock, an acid is produced that dissolves some of the minerals in the rock. Lichen is often called a "pioneer" plant because it is one of the first plants to grow in a rocky area.

1) Chemical and biological sedimentary rocks are produced by chemical weathering instead of the siliciclastic sediments which are created by physical weathering. Because physical weathering is much more often than the chemical weathering there are 10 times more clastic sediments in the earth's crust than chemical and biological sediments.

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.
Chemical weathering often refers to the chemical reactions that take place between acidic rain or ground water and various rock types. It can also refer to the gradual oxidation of minerals by exposure to air and water. The chemical reaction usually results in the gradual dissolution of the rock.
The new solid formed after a chemical reaction is often called the precipitate but not necessarily.
Rock can be transformed into soil by erosion by many means, including river erosion, but also by other means. Soil may also be formed by weathering, though not often, as weathering tends to be crude.
Tafoni, also called 'honeycomb weathering' are a group of significant pits formed in the surface of a rock. Very common in coastal areas, where the regular wet-dry cycles are obvious. Caused by differential weathering of the rock, and the 'lands' between the pits are often quite thin and lacy in appearance. The presence of salt is thought to be an important feature of this type of weathering.

Chemical energy is potential energy until the chemical reaction puts atoms and molecules in motion. Heat energy (KE) is often the result of a chemical reaction.
Acid does indeed cause weathering. It is a common form of chemical weathering, and is sometimes influenced by humans. It is particularly devastating to basic rocks like limestone which neutralise the acid rain, but at the expense of its own volume, as after the neutralisation, the salt is often washed away and the limestone is consequently worn away.
