How do you know if a compound is more soluble in water or acid?
For AgI adding H+ forms HI and that is a strong acid; therefore, AgI is NOT more soluble in acid than in water. For KClO4, adding H+ forms HClO4 but that is a strong acid so it is NOT more soluble in acid. For CuBr adding H+ forms HBr and that is a weak acid; therefore, CuBr is more soluble in acid than in water.
What do we call a calcite formation on a cavern floor?
A stalagmite (UK: /ˈstæl. Stalagmites are typically composed of calcium carbonate, but may consist of lava, mud, peat, pitch, sand, sinter and amberat (crystallized urine of pack rats). The corresponding formation hanging down from the ceiling of a cave is a stalactite.
Where is there karst topography present in our state?
Karsts are found in widely scattered sections of the world, including the Causses of France; the Kwangsi area of China; the Yucatán Peninsula; and the Middle West, Kentucky, and Florida in the United States.
How do you tell if a base is soluble or insoluble?
Bases can be either water soluble or insoluble. Insoluble bases react with acids, directly dissolving in the acid as they react. Soluble bases form hydroxide ions in solution, that then react with the acid as described in the above section Acids, bases and water.
What is the difference between stalactites and stalagmites?
Stalactites grow down from the cave ceiling, while stalagmites grow up from the cave floor. It’s easy to remember which is which: Stalactites have a “T” for top and stalagmites have a “G” for ground. Speleothems actually form because of water. Rainwater seeps through cracks in the rock.
How are stalactites formed in caves?
As the redeposited minerals build up after countless water drops, a stalactite is formed. If the water that drops to the floor of the cave still has some dissolved calcite in it, it can deposit more dissolved calcite there, forming a stalagmite. Speleothems form at varying rates as calcite crystals build up.
