Carbon Dioxide from the atmosphere combines with water to form carbonic acid, it is a form of acid rain.

The primary agent of chemical weathering is water.
The most important weathering agent is water.Water dissolve soluble materials transforming rocks.
Chemical weathering - the rock is dissolved by rain-water acidified slightly by absorbed atmospheric carbon-dioxide.
A plant can act as an agent of mechanical weathering by simply growing next to something. The plant will rub against it and in some cases grow in any openings in the material. Tree roots can grow into the cracks in boulders and ledges, widening these cracks and ultimately contributing to the break-down of these structures. Plants also produce oxygen gas which contributes to chemical weathering through the formation of metal oxides. Tree roots also take nutrients and minerals from the soil, ultimately leaving them on top of the ground and subject to erosion forces.

Karst topography is formed by chemical weathering, and affects the underlying carbonate rock (limestone or dolomite). This occurs under specific drainage conditions. Slightly acidic water (carbonic acid in solution) is the active agent.
