Question

In this experiment, a coil of copper wire is reacted with silver nitrate solution. We can determine whether copper(I) nitrate or copper(II) nitrate is formed as the product along with silver metal. Depending on the product formed, the balanced chemical equation will be one of two possibilities: AgNO3(aq) + Cu (s) CuNO3(aq) + Ag(s)      2AgNO3(aq) + Cu (s) Cu(NO3)2(aq) + 2Ag(s)

Substance Beaker AgNO3 solid Copper wire before reaction Copper wire after reaction Beaker and dried Ag Mass g 50.7 g 1.7063g 3.7199g 3.3897g 51.7g

Explanation / Answer

mass of copper wire before reaction = 3.7199 g

mass of copper wire after reaction = 3.3897 g

The decrease in mass is the copper that is reacted

So,

mass of copper reacted = mass of copper wire before reaction - mass of copper wire after reaction

= 3.7199 g - 3.3897 g

= 0.3302 g

Answer: 0.3302 g
