What is the equation when Ammonium oxalate is added in calcium chloride solution?
The chemical equation when ammonium oxalate is added to a calcium chloride solution is: (NH4)2C2O4 + CaCl2 -> CaC2O4 + 2NH4Cl This reaction forms calcium oxalate (CaC2O4) and ammonium chloride (NH4Cl) as the products.
What is the equation when ammonium oxalate is added in calcium carbonate solution?
The chemical equation for the reaction between ammonium oxalate and calcium carbonate is: (NH4)2C2O4 + CaCO3 → CaC2O4 + 2NH4Cl This reaction forms calcium oxalate (CaC2O4) and ammonium chloride (NH4Cl) as the products.
What is the moles of CaC2O4 x H2O or CaC2O4 precipitated?
21
What is the molar solubility of CaC2O4 Ksp 2.3 x 10 -9 in a 0.15 M Ca2 solution?
To determine the molar solubility of CaC2O4 in a 0.15 M Ca2+ solution, you can set up an ICE table and use the Ksp value. Since CaC2O4 dissociates into Ca2+ and C2O4^2-, and the initial Ca2+ concentration is 0.15 M, you can calculate the concentration of Ca2+ that reacts with C2O4^2- to reach equilibrium. The molar solubility of CaC2O4 can then be determined based on the stoichiometry of the reaction.
What type of electrolyte is CaC2O4?
Calcium oxalate (CaC2O4) is a salt that can dissociate in solution to produce calcium ions (Ca^2+) and oxalate ions (C2O4^2-), making it an electrolyte. It conducts electricity in solution by carrying these charged particles.
What is the balanced equation of calcium chloride and sodium oxalate?
The balanced equation for the reaction between calcium chloride (CaCl2) and sodium oxalate (Na2C2O4) is: CaCl2 + Na2C2O4 → CaC2O4 + 2NaCl
When calcium nitrate reacts with sodium oxalate what by-products should be produced?
The reaction between calcium nitrate and sodium oxalate should produce calcium oxalate as a by-product, along with sodium nitrate. Calcium oxalate is insoluble in water and will precipitate out of solution, while sodium nitrate will remain dissolved.
Chemical Formula For Calcium Oxalate?
The chemical formula for Calcium Oxalate is CaC2O4
What is the name of the compound CaC204?
Calcium oxalate
What is the ionic compound CaCs2O4?
There is no compound by the formula CaCs2O4. However CaC2O4 is calcium oxalate.
What is the oxidation number of cac2o4?
The oxidation number of Ca in CaC2O4 is +2 because Ca, a group 2 element, typically has a +2 oxidation state in compounds. The oxidation number of C in C2O4 is +3 because the overall charge of the oxalate ion is -2, and there are two C atoms, each with an oxidation state of +3 to balance the charge.
Formula for oxalate?
-^OOC-COO^- is the oxalate anion. In modern nomenclature it is 'ethandioate'. Oxalic Acid is Ethan-di-oic acid. (HOOC-COOH)
