White Phosphorous

A colourless inorganic salt (A) decomposes completely at about 250^@ C to give only two products (B) and ( C) , leaving no residue. The oxide ( C) is a liquid at room temperature and neutral to litmus paper while the gas (B) is a neutral oxide. White phosphorous burns in excess of (B) to produce a strong white dehydrating agent. Write balanced equations for the reactions involved in this process.

A white 'A' on heating decomposes to produce two products 'B' and 'C'. 'B' on reaction with white phosphorous produces 'D', which is a strong dehydrating agent. 'D' on reaction with perchloric acid converts it to its anhydride. The compound 'A' is:

There are some deposits of nitrated and phosphates in the earth's crust. Nitrates are more soluble in water. Nitrates are difficult to reduce under laboratory conditions but microbes do it easily. Ammonia forms a large number of complexes with transition metal ions. Hybridisation easily explains the ease of sigma donation capability of NH_3 and PH_3 . Phosphine is a flammable gas and is prepared from white phosphorous. White phosphorous on reaction with NaOH gives PH_3 as one of the products. This is a.

A white 'A' on heating decomposes to produce two products 'B' and 'C'. 'B' on reaction with white phosphorous produces 'D', which is a strong dehydrating agent. 'D' on reaction with perchloric acid converts it to its anhydride. The product obtained on hydrolysis (complete) of D is:

A white 'A' on heating decomposes to produce two products 'B' and 'C'. 'B' on reaction with white phosphorous produces 'D', which is a strong dehydrating agent. 'D' on reaction with perchloric acid converts it to its anhydride. The number of moles of H_(2)O needed to hydrolyse (complete) 1 mole of D is:

An inorganic salt (A) is decomposed at about 523 K to give products (B) and (C).Compounds (C) is a liquid at room temperature and is neutral to limus paper while oxide (B) on burning with white phosphorous given a dehydrating agent (D). Compounds (A),(B),(C) and (D) will be identified as
