(a)The reaction forms an insoluble preceiptate of ferric chloride, FeCl3 (s). The net reaction can be shown as:
Fe3+(aq) + 3CL-(aq) ----> FeCl3(s)
(b)to get smoke free of charged particle we are using cottrell’s smoke precipitator as the smoke coming out of chimney has charged particle of carbon so to neutralise it a oppositely charged plate called cottrells smoke precipitator is used
(c)physisorption involves van der wall attractive forces between adsorbent and adsorbed , This may result on the accumulation of many layers of the molecules on the surface.Chemosorption involves formation of chemical bonds between adsorbent and adsorbed molecule
