2. . Calcium carbonate is only sparingly soluble in water. Assume you start with a saturated solucionet calcium carbonate in contact with undissolved solid i.e. at equilibrium), and then make each of the calcium ions increase, decrease, no change). Give reasons (or an equation) for any changes the following changes to it. Predict the effect of each change upon the concentration of dissolves occur. Nature of change Effect on [Ca2+(aq)] ES The solution is stirred more vigorously Some Na2CO3 is dissolved in the solution Some NaCl is dissolved in the solution HCI is added
