The mineral calcite is a major component of rocks known as limestone. Limestones are very abundant and are quarried for crushed stone and dimension stone for use in concrete, road paving, fill and construction of buildings and homes. Calcite is found both as a bulk component of limestone and as a discrete mineral in open spaces where the limestone has cracked or in irregular openings called vugs and quartz lined cavities called geodes.
Calcite is only slightly soluble in water (0.0145 gram per liter of water at 17oC = 63oF). It is much more soluble in water that has dissolved carbon dioxide gas in it. This property of calcite causes limestone to dissolve when groundwater flows through it. Where the limestone is dissolved and eaten away by carbon dioxide charged groundwater, openings called caves and sinkholes are left behind. When groundwater that is saturated with dissolved calcite reaches an open space, like a cave, the carbon dioxide dissolved in it turns into a gas again and the water can no longer hold as much calcite. The excess calcite precipitates out as cave formations (stalactites and stalagmites) or as a type of rock called travertine. This interesting property of calcite leads to places of great beauty such as caves and also creates hazards such as sinkholes
that may collapse underneath us.
Calcium carbonate, used in gasoline spill site remediation can form calcite. Certain chemical reactions with farm chemicals {fertilizers such as
amonium nitrate}, may occur to form calcium oxilate. This is, interestingly enough, the same chemical composition as kidneystone formations in
a human. Since the function of the human kidney is to filter the blood, theoretically, kidneystones may be formed from consumption of well water
contaminated by a specific combination of farm chemicals, and the chemicals used to remediate gasoline spill sites, such as a leaking gasoline
underground storage tanks. According to EPA sources, millions of gallons of refined gasoline are released into our groundwater from leaking gasoline underground storage tanks DESPITE the repalcement of old style tanks, and DESPITE the implementation new requirements for these tanks.
**Thoeretically... this is how calcium oxilate could be found in the urine of children.
According to thermogravimetric data from DSC analysis, the first step releases water to form the anhydrous salt but upon further heating this step is followed by an oxidative (disproportionation) decomposition step in which carbon monoxide and calcium carbonate are formed. The third and final step is the decomposition of calcium carbonate to form calcium oxide and carbon dioxide. Because of step 2, good ventilation should be used during decomposition of calcium oxalate.
Calcium carbonate Calcium Sulphate Calcium phosphate Calcium chloride/halogens & Calcium nitrates remain in solution. Remember Carbonates, sulphates and phosphates precipitate , or are very sparingly soluble. All nitrates and halogen salts are soluble. All Group (I) metal ( Alkali metals) salts are soluble.
Plants have a crystal formation called raphides which are?æthe chemical compound calcium oxalate crystal. It is a poisonous substance of the plant that can cause soreness and numbness when ingested.
Not by themselves, because they are both too electropositive. Together with oxygen, however, they form calcium aluminate.
We know that the alkaline earth metal calcium (Ca) and the halogen bromine (Br) form the ionic compound calcium bromide (CaBr2). Here's the reaction: Ca + 2Br => CaBr2
no
The net ionic equation for the formation of calcium oxalate is Ca^2+(aq) + C2O4^2-(aq) -> CaC2O4(s). It represents the reaction of calcium ions and oxalate ions to form the insoluble salt calcium oxalate.
The most common composition of kidney stones is calcium oxalate, which accounts for about 70-80% of all cases. These stones can form when there is too much calcium or oxalate in the urine, often influenced by dietary factors, dehydration, or certain metabolic conditions. Other types of kidney stones include uric acid, struvite, and cystine stones, but they are less prevalent than calcium oxalate stones.
Calcium, strontium and Barium form white precipitates of their oxalates with C2O4-2 ions.
Calcium stones are the most common type of kidney stones, typically composed of calcium oxalate or calcium phosphate. They form when there is an excess of calcium in the urine, leading to crystallization and eventual stone formation in the kidneys or urinary tract. Risk factors for calcium stones include dehydration, high salt intake, and certain medical conditions like hyperparathyroidism.
Calcium forms in the bladder primarily through the precipitation of calcium salts when urine becomes supersaturated with calcium and oxalate or phosphate. Factors contributing to this include dehydration, high dietary calcium intake, or metabolic disorders. When these conditions exist, minerals can crystallize and aggregate, leading to the formation of bladder stones or calcifications. This process can be influenced by urine pH and other urinary constituents.
Sulfuric acid is used in titration of oxalate ion as it reacts with oxalate ion to form a white precipitate of calcium oxalate, which makes it easier to detect the end point of the titration. The strong acidity of sulfuric acid also helps in preventing the hydrolysis of the calcium oxalate precipitate.
According to thermogravimetric data from DSC analysis, the first step releases water to form the anhydrous salt but upon further heating this step is followed by an oxidative (disproportionation) decomposition step in which carbon monoxide and calcium carbonate are formed. The third and final step is the decomposition of calcium carbonate to form calcium oxide and carbon dioxide. Because of step 2, good ventilation should be used during decomposition of calcium oxalate.
Calcium stones are the most common type of kidney stone and occur in two major forms: calcium oxalate and calcium phosphate. ...Uric acid stones form when the urine is persistently acidic. ...Struvite stones result from kidney infections
Black, jagged, and sharp kidney stones are typically composed of calcium oxalate. These stones can form when there is an excess of oxalate in the urine or when calcium levels are high. The sharp edges can cause significant pain as they move through the urinary tract. Other factors, such as dehydration and diet, can also contribute to their formation.
Kidney stones are made up of various minerals and waste products that can form crystals in the urine. The most common types of kidney stones are calcium oxalate, uric acid, struvite, and cystine stones. The specific composition can vary depending on the individual and the type of kidney stone.
Accumulation of oxalate in the body can lead to formation of kidney stones, as oxalate binds with calcium to form insoluble crystals. This can result in kidney damage, pain, and urinary tract issues. In severe cases, high oxalate levels can lead to kidney failure.
