sample analysis was recently demonstrated for the determination of Cu and Zn in fruit juice and bovine milk samples [16]. In this work, TSFFAAS was employed for Cu, Mn, Pb, and Zn determination in beer without sample digestion. The adopted dilution factors were chosen depending on the analyte and sample characteristics to generate signals in the

What Is Zn + Pb(NO3)2? |

The chemical equation Zn + Pb(NO3)2 refers to solid zinc added to a solution of lead nitrate, which produces solid lead and a solution of zinc nitrate. The balanced equation is Zn + Pb(NO3)2 > Pb + Zn(NO3)2. For example, 1 gram of zinc is dropped into 10 milliliters of a lead nitrate solution.
