WebDemo-033. Lime Water/Carbon Dioxide Reactions. The addition of carbon dioxide gas to lime water, Ca (OH)2 (aq), first results in the precipitation of CaCO3. Additional CO2, however, redissolves the precipitate. The reaction can be reversed to give the CaCO3 precipitate once again either by boiling the solution or bubbling air through it. WebThe reason gas leaks are so dangerous is that they can cause damage in two very different ways. Over time, the buildup of leaked gas can cause a large explosion in the presence … hof jostmeier
