A student prepared a sample of silicon chloride by passing chlorine over heated silicon and collecting the condensed silicon chloride in a small specimen tube. He analsed the chloride by dissolving a known mass of it in water and titrating the solution with standard silver nitrates solution. The formula of the silicon chloride as obtained by this method was SiCl_(2.6) as aganist a true formula SiCl_(4). Which of the following possible errors could have resulted in this wrong formula?

1.	A student prepared a sample of silicon chloride by passing chlorine over heated silicon and collecting the condensed silicon chloride in a small specimen tube. He analsed the chloride by dissolving a known mass of it in water and titrating the solution with standard silver nitrates solution. The formula of the silicon chloride as obtained by this method was SiCl_(2.6) as aganist a true formula SiCl_(4). Which of the following possible errors could have resulted in this wrong formula?
Answer» The silicon chloride contained excess dissolved chlorine. More silicon chlorine than the student supposed was actually USED owing to inaccurate weighing The small SPECIMENT tube was not dry The reaction between the silicon and the chlorine stopped permaturely LEAVING some unreacted silicon in the reaction tube Answer :C
