Draw suitable resonance structures to explain this observation. Sulfite (SO32-) anions also have S-O bonds of equal lengths but these are different to sulfate lengths. Identify the system with the shorter bond length and explain your reasoning.7. (a) Discuss the viscosity method for calculating the molecular mass of polymers.
