CaCO3(s)+2H+(aq)→Ca2+(aq)+H2O(l)+CO2(g)若当酸性的水流经地下岩石时，就在地下形成了溶洞 （cave）。若水中溶有CO2,则还会存在以下平衡：CaCO3(s)+CO2(aq)+H2O(l)＝Ca2+(aq)+2HCO3－(aq)当含有Ca2+(aq)和HCO3－的地下水从溶洞的顶向下滴落时，其中的水和二氧化碳会挥发，平衡向左移动，...
For dissolution in NDW and CSW, the mean values of log IAP (Ion activity products) in the final stable state (≈ log Ksp, Solubility product constants) were determined to be − 8.65 ± 0.04 and − 8.16 ± 0.11 for calcite [CaCO3], respectively; − 8.50 ±...
Write the balanced equation for an acid-base reaction that would produce CaF_2. Predict whether an aqueous solution of the given salt is acidic, basic, or neutral. Write balanced equations and expressions for K_{sp} for the dissolution of each ionic compo...
If the product of concentration of Ca++ ions and SO4−2ions exceeds the solubility products (KSP) of CaSO4, calcium sulfate would be precipitated. The solubility of calcium sulfate decreases with an increase in the temperature. CaCO3 and CaSO4 scaling cause major problems in plants and ...
