• In this work, samples from two stone types with different porosity were treated with ammonium oxalate (AmOx) to create a protective layer of calcium oxalate (CaOx) using the previously developed brushing method. (irb.hr)
  • I am puzzled about something that occurs when I precipitate calcium oxalate. (sciencemadness.org)
  • This highly palatable complete diet is specially designed to ensure the production of a large volume of moderately acidic urine with low struvite and calcium oxalate Relative. (pet-supermarket.co.uk)
  • Thus the urine is unfavourable to the development of both Struvite and calcium oxalate crystals. (pet-supermarket.co.uk)
  • Other, less common staghorn calculi can be composed of mixtures of calcium oxalate and calcium phosphate. (medscape.com)
  • Although calcium oxalate stones are most prevalent in the Western world, struvite calculi account for up to 30% of urinary tract stones worldwide. (medscape.com)
  • 1) Adding calcium chloride soln to potassium oxalate soln gives an abundant precipitate instantly, as expected. (sciencemadness.org)
  • It is the ammonium salt of oxalic acid, and occurs in many plants and vegetables. (wikipedia.org)
  • citation needed] Acid ammonium oxalate (ammonium oxalate acidified to pH 3 with oxalic acid) is commonly employed in soil chemical analysis to extract iron and aluminium from poorly-crystalline minerals (such as ferrihydrite), iron(II)-bearing minerals (such as magnetite) and organic matter. (wikipedia.org)
  • Royal Canin urinary diet will dissolve and prevent occurrence of struvite and prevent spontaneous homogeneous crystallisation of oxalate. (pet-supermarket.co.uk)
  • 2) Adding calcium chloride soln to ammonium iron (III) oxalate soln also gives an abundant precipitate, but it forms over a number of seconds. (sciencemadness.org)
  • 3) Adding a drop or two of iron (III) chloride soln to the ammonium iron (III) oxalate soln, before adding the calcium chloride, either results in no precipitate or one that takes many minutes (or an hour) to occur and then it is not abundant. (sciencemadness.org)
  • I would have thought that iron (III) chloride would be a by-product of the reaction between calcium chloride and ammonium iron (III) oxalate. (sciencemadness.org)
