Question:

The following series of observations is made: 

(1) A small piece of dry ice [CO2(s)] is added to 0.005 M Ca(OH)2(aq). 

(2) Initially, a white precipitate forms.

(3) After a short time the precipitate dissolves.

(a) Write chemical equations to explain these observations.

(b) If the 0.005 M Ca(OH)2(aq) is replaced by 0.005 M CaCl2(aq), would a precipitate form? Explain.

(c) If the 0.005 M Ca(OH)2(aq) is replaced by 0.010 M Ca(OH)2(aq), a precipitate forms but does not re-dissolve. Explain why.
