Question

How is phosphine prepared using the hcl,h2so4,caustic soda

Answer 1

Preparation of Phosphine using $HCl, H_2SO_4$ and Caustic soda

Phosphine using HCl

• When dilute HCl reacts with calcium phosphide, it leads to the production of phosphine and calcium chloride.
• The chemical reaction involved is
• $Ca_3P_2+6HCl\rightarrow 3CaCl_2+2PH_3$

Phosphine using $H_2SO_4$

• When aluminium phosphide is treated with $H_2SO_4$, it produces phosphine along with aluminium sulfate.
• The chemical reaction involved is
• $2AlP+3H_2SO_4\rightarrow Al_2(SO_4)_3+2PH_3$

Phosphine using caustic soda $(NaOH)$

• When white phosphorus is treated with $NaOH$ and $H_2O$, it yields phosphine and sodium hypophosphite.
• The reaction involved is
• $P_4+3NaOH+3H_2O\rightarrow PH_3+3NaH_2PO_2$
