pH describes how acidic or basic the liquid is. A very low pH...say 1.5...is extremely acidic and and a pH of 11 would be very caustic. In the case of weathering rock you are usually talking about acid rain...rain with a pH below 7. The acid attacks the chemical bonds in the stone and causes accelerated weathering.

Which statue is likely to be affected most in chemical weathering marble or granite statue?
A marble statue is likely to be affected more by chemical weathering compared to a granite statue. Marble is a softer and more porous rock than granite, making it more susceptible to chemical reactions with acids in the environment, such as acid rain. This can lead to the erosion and disintegration of the marble statue over time.
What chemical weathering process would a marble rock undergo?
Dissolution by water, especially water acidified by atmospheric carbon dioxide (producing carbonic acid) or soil acids. Marble is composed primarily of the mineral calcium carbonate, modified to crystalline form by metamorphism of the parent limestone. Therefore karst features can develop in marble just as they can in unaltered limestone.
What reacts with water to dissolve rocks such as marble and limestone?
Carbon dioxide reacts with water to form carbonic acid, which then reacts with minerals in rocks like marble and limestone, causing them to dissolve. This is known as carbonation weathering and is a common process in the dissolution of carbonate rocks.
Is acid rain weathering a marble statue a physical change or a chemical change?
Chemical change
What causes small holes to form in marble steps and statues?
Small holes in marble steps and statues can form due to a variety of factors such as erosion from water and chemicals, weathering from exposure to the elements, or biological activity from microorganisms breaking down the surface. Additionally, physical stress or impact can also contribute to the formation of small holes in marble.
What is the pH of marble?
pH is measured only in solutions or liquids. Marble chips has not a pH.
What is the pH of marble chips?
pH is measured only in solutions or liquids. Marble chips has not a pH.
What types of weathering effect marble?
nnnnnnnnnnnnnnnnnnnnnnoooooooooooooooooooooooooooooooooooooooooooooo
Would weathering affect a marble sculpture inside a museum?
If the marble sculpture is not in a climate controlled environment, it would be affected by a limited amount of weathering, yes.
What weathers marble and limestone?
carbon dioxide: when it mixes with rain& water will create carbonic acid rain which weathers marble and limestone.so carbonic acid weathers marble and limestone.
How does the type of rock affect weathering?
The Rock Composition really affects the rate of weathering because different types of rocks will react differently to water and other substances. If you pour water on flat marble and leave it, the water would usually leave a mark or a stain on marble depending on what color the marble is. If the marble is black, the stain would have a high chance of being gray. If you pour water on a slab of limestone, the water would have a high chance of just passing through. After a few times of pouring, the slab of limestone would have like an indent if all of the ours were in the same place.
Minerals resistant to chemical weathering?
Quartz is a mineral that is highly resistant to chemical weathering. Marble is a mineral that is more susceptible to chemical weathering.
Which weathers faster feldspar or marble?
Marble weathers faster than feldspar because marble is more susceptible to chemical weathering due to its composition of calcium carbonate, which reacts easily with acidic rainwater. In comparison, feldspar is more resistant to weathering due to its hardness and chemical stability.
What type of weathering could act on a gravestone?
Simply rain, gravestones are frequently made of marble and marble is etched by rain.
How to clean marble tiles effectively?
To clean marble tiles effectively, use a mild detergent or a pH-neutral cleaner mixed with water. Avoid acidic or abrasive cleaners that can damage the marble. Gently scrub the tiles with a soft cloth or mop, then rinse with clean water and dry thoroughly to prevent water spots. Regularly seal the marble to protect it from stains and maintain its shine.
What do you clean marble with to maintain its pristine appearance?
To maintain the pristine appearance of marble, clean it with a mild detergent or a pH-neutral cleaner and water. Avoid using acidic or abrasive cleaners that can damage the surface. Regularly wipe up spills and avoid leaving standing water on the marble surface.
Why would a marble statue last longer in a dry desert?
Marble is attacked by carbonic acid - carbon dioxide dissolved in water. The desert has little rainfall so chemical weathering occurs at a very slow rate.
