Industrial removal of soluble impurities, repeated immersion of coarse salt filtration with saturated sodium chloride solution is why? Crude salt contains insoluble impurities such as sediment,And soluble impurities such as Ca 2,Mg 2,2-Wait.Insoluble impurities can be removed by filtration,Ca 2 in soluble impurities,Mg 2,2-The solution of BaCl2, sodium hydroxide and sodium carbonate can be added,Precipitation filtering is generated and removed.Instruments for crude salt purification: pallet balance (including weights ),Cylinder,Beaker,Glass rods,Spoon,Funnel,Filter paper,Iron frame (with iron ring ),Pan,Alcohol lamp,Pliers,(1) Take 2 grams of coarse salt (accurate to 0) by pallet Tianping.1G ).Use the measuring cylinder to take 10 ml water and pour it into the beaker and stir it with a glass stick,Until the crude salt is no longer dissolved.(6) add a proper amount of HCl to the filter (remove excessive sodium hydroxide and sodium carbonate, you can choose to control the amount added with pH test
Is it better to buy bottled water, or to use a filter device to drink water directly? It will be healthier and more cost-effective to install water purifiers,
