Question
1. )
One industrial method of producing bromine is to react seawater, containing a low concentration of sodium bromide, with chlorine gas. The chlorine gas is bubbled through the seawater in a specially designed vessel. Write the net ionic equation for this reaction.
2.)
A lab technician uses 1.0 M Na2CO3(aq) to precipitate metal ions from waste solutions. the resulting filtered solids can be disposed of more easily than large volumes of solution. Write net ionic equations for the reaction between Na2CO3(aq) and each of the following waste solutions.
Zn(NO3)2(aq)
Pb(NO3)2(aq)
Fe(NO3)3(aq)
AgNO3(aq)
NiCl2(aq)
Explanation / Answer
ans 1
ans 2
Zn²(aq) + CO²(aq) ZnCO(s)
Pb²(aq) + CO²(aq) PbCO(s)
Fe²(aq) + CO²(aq) FeCO(s)
2Ag(aq) + CO²(aq) Ag2CO(s)
Ni 2+(aq) + CO32-(aq) -> NiCO3(s)
Ionic Equation: Cl2 (aq)+ 2 Br- (aq) 2 Cl- (aq) + Br2 (aq)Related Questions
