Can granite dissolve slowly in acid water to form caves?
No, only limestone dissolves.
What is a substance in the air which made limestone change?
Limestone is basically calcium carbonate. *All* acids will slowly cause the surface of limestone to dissolve thus eroding the surface. The stronger the acid, the quicker the dissolution. Acids based on sulfur, such as sulfurous or sulfuric acids are very harmful to limestone.
If a limestone piece is dipped in water a bubble evolves Why?
Weak acid reacts with the limestone (calcium carbonate (CaCO3), to form hydrogen carbonate HCO3- ions (which is soluble in water). Therefore, acid rain has the same effect, and is the cause of pot holes and caverns in limestone areas.
How does limestone react when exposed to weak acids?
If the water contains any carbonic acid (if its rain water) then it will slowly dissolve/disintegrate the limestone.
Does carbonic acid melt limestone?
No, it can't. Limestone melts only at high temperatures. But carbonic acid can, over the course of time, attack and dissolve a lot of limestone. Here's the deal, and it's on the mark. The atmosphere contains mostly nitrogen and oxygen as you know, but there's a bit of darbon dioxide in there, too. And water in the air picks up CO2 and becomes carbonic acid. This is carried to earth in rain. This doesn't "affect" rain all that much, but it does lower the pH of rain a bit. And the carbonic acid, though it is weak, will seep into the ground where limestone layers form an under layer and slowly, over the course of geologic time, dissolve the limestone to create some fantastic caves!
Does limestone weather slowly or quickly?
Relative to other rock types, limestone is on the 'easily weathered' end of the scale.
What type of chemical weathering is associated with limestone?
Normal rain (slowly) and acid rain (rapidly) both weather limestone.
Two identical statues are placed outside one is made of limestone the other made of granite Which statue will weather more slowly?
Since granite is an igneous rock this makes it highly resistant to weathering. Therefore, granite will weather more slowly than limestone.
Which statue will weather more slowly a granite one or a limestone one?
Granite will weather more slowly, since it is an igneous rock and is extremely resistant to weathering.
Two identical statues are placed outsideone is made of limestone the other made of granite Which statue will weather more slowly?
I'll say granite because the limestone as you know, is faster to it's weathering.
What substance in rainwater makes it so limestone weather easier than sandstone?
Carbon dioxide dissolved in rain water forms a weak acid which slowly weathers limestone, a carbonate which reacts with acids.
Does carbonic acid dissolve limestone?
No. It dissolves limestone slowly. It may take centuries for a limestone outcrop to show visible weathering.
What is the word that can make limestone rocks slowly dissolve away?
That would be erosion.
What does dilute hydrochloric acid do to limestone?
when acid is on limestone to start with there would be a continues fizz. After time acid would were slowly chip and were away the rock.
Can granite dissolve slowly in acid water to form caves?
No, only limestone dissolves.
What reacts with water to produce limestone caves?
Carbon dioxide dissolves in water forming carbonic acid H2CO3, a weak acid that slowly erodes the limestone.
Why are no caves formed in feldspar?
Feldspar is a constituent of igneous rocks, primarily granite, and does not form rock masses alone. Also, although it does weather, very slowly, neither it nor the igneous rocks generally have the solubility of limestone. Caves do form in granite etc by subaeriel, sea or riverine erosion, but they are generally small, shallow rock-shelters, not conduits as in limestone caves.
