Non Polar The bonds themselves between phosphorus and chlorine are polar because chlorine is more electronegative than phosphorus.However the molecule is non polar because th â¦ e five regions of electron density are the same.1 person found this useful.he â¦ bond  angles are less than tetrahedral, 93 o compared to  tetrahedral angle of 109.5 o, there are four electron  pairs, three bonds and the lone pair give the molecule a distorted  tetrahedral electron arangement, (VSEPR thoery).
Poly Aluminium Chloride-PAC. These compounds have the general formula (Al n (OH) m Cl (3n-m))x and have a polymeric structure, totally soluble in water. The length of the polymerised chain, molecular weight and number of ionic charges is determined by the degree of polymerisation.he reaction. Where we can produce, in the glass line reactor, polyaluminum chloride coagulants with a low and medium basicity. The most important is PAC 18 a liquid coagulant potable grade approved and it is an effective coagulant for treatment of both potable and waste water treatment.
