    I have a selection of apparatus and materials that I could use to prepare a gas jar of dry phosphine. I have the following pieces of apparatus to use:-
    Wash bottle
    Polythene connectors
    Dropping funnel with rubber stopper
    Bent glass tube
    Filter funnel with paper
    U-tube
    Porcelain boat
    Gas jar
    Round bottomed flask with side arm

    The materials/substances that I have available are as follows :-

    Concentrated hydrochloric acid
    Water
    Calcium chloride granules
    Salt
    Calcium phosphide
    Calcium Carbonate

    Now, I do not think I will be needing the porcelain boat, filter funnel with paper, hydrochloric acid and salt. I think that I will require all of the rest of the above mentioned apparatus. I have a very good idea of how these will go together to enable me to collect the dry phosphine gas at the end, but I need to be sure on this.

    I also think that I will need to add the calcium chloride granules into the u tube to dry the gas and that I will need to upturn the gas bottle at the end to catch the gas.

    Please can you help. I have a picture of all of the apparatus in front of me, but hopefully you will be aware of what I am using by my descriptions.

    To make Phosphine in laboratory, we would need the following equipment.
    Syringe and glass tube for washing gas burette is optional, 100 mL gas burette with threaded top.
    Screw top with septum and syringe guide.
    Funnel (narrow neck) with wire and weight attached.
    Water reservoir with tap at bottom.
    The reservoir is filled with water.
    After placing the funnel into the bottom of the reservoir (with the wire hanging over the edge), the gas burette is lowered into ...
