How do you make muddy muddy water clear?
1, filter. 2, to which access to carbon dioxide, calcium carbonate and carbon dioxide and water reaction of soluble calcium bicarbonate, thus become clear.
Continue to pass through the CO2 gas and continue to pass, as followsCaCO3+H2O+CO2==Ca (HCO3) 2 can be clarifiedIf specific operations are needed, blow it into muddy lime waterOr by adding too much hydrochloric acid, the calcium carbonate dissolved
Add dilute hydrochloric acid, precipitate (calcium carbonate) into calcium chloride and dissolve.= CaCO3+2HCl=====CaCl2+H2O+CO2The amount of carbon dioxide, calcium carbonate and calcium bicarbonate dissolved into.CaCO3+CO2+H2O====Ca (HCO3) 2But adding solution or adding some alkaline substance will produce calcium carbonate precipitation again.Ca (HCO3) 2==== ===CaCO3: +CO2 = +H2O heatingCa (HCO3) 2+Ca (OH) 2======2CaCO3: +2H2O
