Cl= 35.45 g/m Silver nitrate should be stored in cool, dark areas, away from sources of physical damage, and ignition. After sitting for awhile, the white will settle to the bottom. If the investigation of a property involves an attempt to change the substance into another substance, that property is a chemical property. Copper Metal (Cu) + Silver Nitrate (AgNO 3) = Silver Metal (Ag) + Copper Nitrate (CuNO 3) Outcome As the silver nitrate is converted into its elemental form, the deposits of silver coat the surface of the copper wire where they continue to accumulate over time. The blue colour of the copper (II) sulfate solution fades. One day of lead time is required for this project. Experts are tested by Chegg as specialists in their subject area. B. A chemical change occurred because a new substance was created. This is a type of redox reaction. The silver is reduced to elemental silver and the copper is oxidized to copper(II): Cu(0) + 2AgNO 3 = Cu(NO 3) 2 + 2Ag(0) The silver crystallizes at the surface of the copper and the copper wire quickly becomes coated with a bunch of elemental silver. An important chemical property is the way copper reacts with oxygen. Methylated Spirits Include oxidation numbers and total charge contributions for the elements involved in the reaction.
