Expert Answer 100% (56 ratings) Previous question Next question Get more help from Chegg. For CuCO3, the respective ions are +2 and -2. Review for Ch. Calcium hydroxide Ca(OH) 2 5.5×10 –6. Calculate the solubility of this compound in g/L. Ksp of AB is written: AB(s) <=> A^+n(aq) + B^-n(aq) Ksp = [A^+n][B^-n] So, if A is +2 and B is -2 then you just replace the +n and -n with the appropriate number. The Ksp of calcium carbonate, CaCO3, is 3.36 . Answer 4.5 × 10 −9. Write an expression for Ksp for the dissolution of AgI. The solubility of calcite in water is 0.67 mg/100 mL. At 25°C and pH 7.00, Ksp for calcium phosphate is 2.07 × 10 −33, ... One crystalline form of calcium carbonate (CaCO 3) is the mineral sold as “calcite” in mineral and gem shops. 1 Answer. Write an expression for Ksp for the dissolution of CaCO3. Relevance. The Ksp of calcium carbonate, CaCO3, is 3.36 10-9. Calcium carbonate CaCO 3 2.8×10 –9. Show transcribed image text. Using this concentration and the measured pH = 8.61, calculate KSP of CaCO3. Calcium carbonate, CaCO3 has a solubility product Ksp = 8.7 x 10-9. The Ksp Of Calcium Carbonate, CaCO3, Is 3.36; Question: The Ksp Of Calcium Carbonate, CaCO3, Is 3.36. Calcium phosphate Ca 3 (PO 4) 2 2.0×10 –29. If you have a compound that is 1:1 between the cation and anion it has a formula like AB. Write a balanced equation for the dissolution of PbCl2 b. Calcium sulfate CaSO 4 9.1×10 –6. Calculate its K sp. Comparison of solubility of calcium carbonate with different salts of calcium has shown in table 1, and it can be conclude that only calcium carbonate has an extremely low solubility. Calcium oxalate CaC 2 O 4 2.7×10 –9. Answer Save. Ksp = [Ca2+] [CO32-] (1) If you don't take into account the hydrolysis of the carbonate ion the solubility S is S = [Ca2+] = [CO32-] = Ksp neglecting hydrolysis of CO32(2) The estimated solubility would be 7.1x10-5M. 2.) See the answer. Umar. Calcium chromate CaCrO 4 7.1×10 –4. We need to take into account the hydrolysis of the carbonate ion with K2 = 4.8x10-11: HCO3- H + CO3. The Ksp of calcium carbonate is 5.0x10-9: 2+ 2CaCO3(s) Ca + CO3. Calcium sulfite CaSO 3 6.8×10 –8. CaCO3 = Ca^2+ + CO3^2-Ksp = [Ca^2+][CO3^2-] Now [Ca^2+] = [CO3^2-] = 11.77ppm = 11.7mg/L [Ca^2+] = 11.7/40.08 = 0.292mM, and [CO3^2-] = 11.7/60 = 0.195mM. Lv 7. Calcium fluoride CaF 2 5.3×10 –9. Best Answer 80% (5 ratings) Previous question Next question Get more help from Chegg. … What is the concentration of Ca2+ ions in? This problem has been solved! a. The Ksp expression is fairly easy to write when you figure out the procedure. 3.) Write an expression for Ksp for the dissolution of PbCl2.
