The Ksp of calcium carbonate is 5.0x10-9: 2+ 2CaCO3(s) Ca + CO3. What is the concentration of Ca2+ ions in? 3.) 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. Calcium carbonate, CaCO3 has a solubility product Ksp = 8.7 x 10-9. The Ksp expression is fairly easy to write when you figure out the procedure. Calcium phosphate Ca 3 (PO 4) 2 2.0×10 –29. Calculate the solubility of this compound in g/L. Calcium sulfate CaSO 4 9.1×10 –6. The Ksp Of Calcium Carbonate, CaCO3, Is 3.36; Question: The Ksp Of Calcium Carbonate, CaCO3, Is 3.36. 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. Write an expression for Ksp for the dissolution of CaCO3. Write a balanced equation for the dissolution of PbCl2 b. Using this concentration and the measured pH = 8.61, calculate KSP of CaCO3. Umar. 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.

Expert Answer 100% (7 ratings) Previous question Next question Transcribed Image Text from this Question. Review for Ch. 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. 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. Write a balanced equation for the dissolution of AgI. For CuCO3, the respective ions are +2 and -2. Answer Save. Calcium fluoride CaF 2 5.3×10 –9. Calcium hydrogen phosphate CaHPO 4 1×10 –7. Show transcribed image text. Answer 4.5 × 10 −9. Write an expression for Ksp for the dissolution of AgI. Write an expression for Ksp for the dissolution of PbCl2. Best Answer 80% (5 ratings) Previous question Next question Get more help from Chegg. Calcium oxalate CaC 2 O 4 2.7×10 –9. Relevance. The Ksp of calcium carbonate, CaCO3, is 3.36 10-9. 5 years ago. Calcium chromate CaCrO 4 7.1×10 –4. If you have a compound that is 1:1 between the cation and anion it has a formula like AB. The solubility of calcite in water is 0.67 mg/100 mL. The Ksp of calcium carbonate, CaCO3, is 3.36 . Ksp = [Ca^2+][CO3^2-] = 0.292 X 10^-3 X 0.195 x 10^-3 = 5.694 x 10^-8 . a. Calcium sulfite CaSO 3 6.8×10 –8. See the answer. We need to take into account the hydrolysis of the carbonate ion with K2 = 4.8x10-11: HCO3- H + CO3. Favorite Answer. Calculate its K sp. Calcium hydroxide Ca(OH) 2 5.5×10 –6. … b. a. Lv 7.
