Microscopic imperfections in glass are usually harmless
Microscopic imperfections in glass are usually harmless, but imperfections of nickel(IT) sulfide can cause the glass to crack spontaneously. To study this process, nickel(II) sulfide can be synthesized from sodium suifide and nickel(II) sulfate.
Ni2+(aq)+ SO42-(aq)+ 2Na+(aq)+S2-(aq) →NiS(s) + 2Na+(aq) + SO42-(aq)
(a) Which lons are the spectator lons?
(b) Write the net ionic equation.
