Explain preparation and properties of phosphorus trichloride
It may be prepared by the action of phosphorus on thionyl chloride.P4 + 8SOCl2 4OCl3 + 4SO2 + 2S2Cl2 Lab. Method: it is more conveniently prepared in the laboratory by heating white phosphorus in a current of dry chlorine when phosphorus trichloride distils over.P4 + 6Cl2 4PCl3Phosphorus is gently heated in a retort on a water bath and current dry chlorine is passed. Phosphorus trichloride distils over and is collected in a receiver cooled in freezing mixture.It is redistilled over white phosphorus to remove any phosphorus pentachloride present an impurity.Properties It is colourless fuming liquid. It reacts violently with water forming phosphorus acid.PCl3 + 3HOH H3PO3 + 3HCl It reacts with concentrated H2SO4 forming chlorosulphonic acid. Or, 2H2SO4 + PCl3 HSO3Cl + HPO3 + SO2 + HCl It reacts with organic compounds containing hydroxyl group. It directly combines with Cl2, O2 and S. this indicates that it is an unsaturated compound.PCl3 + Cl2 PCl52PCl3 + O2 2POCl3PCl3 + S PSCl3 It acts as a reducing agent.PCl3 + SO2Cl2 PCl5 + SO2PCL3 + SO3 POCL3 + SO23PCl3 + S2Cl2 PCL5 + 2PSCl3It reacts with finely divided metals when hot.12Ag + 4PCl3 12AgCl + P46Na + PCl3 3NaCl + Na2P
Can someone please help me in getting through this problem. 1.0 gm of pure calcium carbonate was found to require 50 ml of dilute HCL for complete reaction. The strength of the HCL solution is given by: (a) 4 N (b) 2 N (c) 0.4 N (d) 0.2 N
Cyclohexane (C6H12) is produced by mixing Benzene and hydrogen. A process including a reactor, separator, and recycle stream is used to produce Cyclohexane. The fresh feed contains 260L/min C6H6 with 950 L/min of H2
The contribution of an electrolyte, or an ion electrolyte, is reported as the molar of a conductance. The definition of the molar conductance is based on the following conductivity cell in which the electrodes are 1 m apart and of sufficient area that th
Alkyl halides or haloalkanes are the compounds in which a halogen is bonded to an alkyl group. They have the general formula RX (where R is alkyl grou
I) Sulphur dioxide (SO2) with a volumetric flow rate 5000cm3/s at 1 bar and 1000C is mixed with a second SO2 stream flowing at 2500cm3/s at 2 bar and 200C. The process occurs at steady state. You may assume ideal gas behaviour. For SO2 take the heat capacity at constant pressure to be CP/R = 3.267
The two solutions which are having equivalent osmotic pressure are called isotonic solutions. The isotonic solutions at the same temperature also have same molar concentration. If we have solutions having different osmotic pressures then the solution having different
Provide solution of this question. To neutralise completely 20 mL of 0.1 M aqueous solution of phosphorous acid (H3 PO3) the volume of 0.1 M aqueous KOH solution required is: (a) 40 mL (b) 20 mL (c) 10 mL (d) 60 mL
In these reaction oxygen atom of carbonyl group is replaced by either one divalent group or two monovalent groups. Reaction by ammonia derivatives: aldehydes and ketones react with a number of ammonia derivatives such as hydroxylaminem hydrazine, semicarbazide etc. in weak acidic medium.
