Expert Answer 100% (7 ratings) Previous question Next question Transcribed Image Text from this Question. Write an expression for Ksp for the dissolution of PbCl2. Using this concentration and the measured pH = 8.61, calculate KSP of CaCO3. 5 years ago. Calculate its K sp. For CuCO3, the respective ions are +2 and -2. Calcium carbonate CaCO 3 2.8×10 –9. … Calcium chromate CaCrO 4 7.1×10 –4. 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 an expression for Ksp for the dissolution of AgI. We need to take into account the hydrolysis of the carbonate ion with K2 = 4.8x10-11: HCO3- H + CO3. Best Answer 80% (5 ratings) Previous question Next question Get more help from Chegg. Ksp = [Ca^2+][CO3^2-] = 0.292 X 10^-3 X 0.195 x 10^-3 = 5.694 x 10^-8 . Answer Save. Write an expression for Ksp for the dissolution of CaCO3. Show transcribed image text. 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. b. The Ksp Of Calcium Carbonate, CaCO3, Is 3.36; Question: The Ksp Of Calcium Carbonate, CaCO3, Is 3.36. Calcium sulfite CaSO 3 6.8×10 –8. Calcium phosphate Ca 3 (PO 4) 2 2.0×10 –29. Calcium carbonate, CaCO3 has a solubility product Ksp = 8.7 x 10-9. Calcium fluoride CaF 2 5.3×10 –9. The Ksp of calcium carbonate is 5.0x10-9: 2+ 2CaCO3(s) Ca + CO3. What is the concentration of Ca2+ ions in? 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. Write a balanced equation for the dissolution of PbCl2 b. 2.) The solubility of calcite in water is 0.67 mg/100 mL. Umar. Relevance. 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. If you have a compound that is 1:1 between the cation and anion it has a formula like AB. Calcium hydroxide Ca(OH) 2 5.5×10 –6. 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. Favorite Answer. 1 Answer. Calcium sulfate CaSO 4 9.1×10 –6. The Ksp expression is fairly easy to write when you figure out the procedure. Calculate the solubility of this compound in g/L. Review for Ch. The Ksp of calcium carbonate, CaCO3, is 3.36 10-9. Lv 7. Write a balanced equation for the dissolution of AgI. 3.) The Ksp of calcium carbonate, CaCO3, is 3.36 . Calcium hydrogen phosphate CaHPO 4 1×10 –7.
