Kidneys stones are a solid piece of mass most commonly made up of calcium oxalate and are found in the kidney or ureter. Kidneys stones are formed when there is a high concentration of a crystal forming substance such as, calcium, phosphorus, and sodium, and the urine is unable to dilute it. Also, if the urine lacks the substances which prevent the crystals from sticking together, this creates an ideal environment for the stones to form. One type of a very common kidney stone is, calcium oxalate. The build up of the calcium oxalate in the human body can be explained using equilibrium. Calcium oxalate is able to break down into calcium ions and oxalic acid, and the reaction is able to go backwards as well. When calcium oxalate (CaC2O4) is …show more content…

The way the reaction shifts is dependent on various factors which influence the equilibrium and Chatelier's principle. These factors include concentration, temperature, volume, and pressure. The Ksp equation for this reaction is Ksp= [Ca+2][C204-2]. By looking at this equation, you can tell that the reaction is very dependent on the concentration of the calcium ions and the acid. For example, if the Ksp value is too large, that means that the concentration of the products is much too high and the equation will shift to the left producing more calcium oxalate which means more kidney stones will be formed. If the Ksp value is too low, than that means that that concentration of the reactants is much too high and the right reaction will be favoured producing more calcium ions and acid. Going back to Chatelier's principle, if the amount of calcium or oxalic acid is increased from equilibrium then the the reaction will shift to the left making more of calcium oxalate. Therefore if someone were to have a diet high in oxalic acid, they would be more likely to form kidneys stones compared to someone who doesn’t eat a lot of foods with oxalic acid. A very basic and easy way to prevent kidney stones from forming is to drink plenty of water
