Fertiliser Technology Phosphoric acid is produced in wet process from phosphate rock and Concentrated H₂SO₄ Concentrated HCl Concentrated NHO₃ Dilute H₂SO₄ Concentrated H₂SO₄ Concentrated HCl Concentrated NHO₃ Dilute H₂SO₄ ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Ammonium nitrate (is mixed with limestone) is not used as fertiliser as such, because It is a liquid at room temperature It is hygroscopic and explosive in nature Its nitrogen content is very less It is highly acidic in nature It is a liquid at room temperature It is hygroscopic and explosive in nature Its nitrogen content is very less It is highly acidic in nature ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Electric process as compared to wet process (for the manufacture of phosphoric acid) Is weak acid process Can use only high grade phosphate rock Produces a valuable by-product called gypsum Is used less frequently Is weak acid process Can use only high grade phosphate rock Produces a valuable by-product called gypsum Is used less frequently ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Low grade phosphate rock can be used in electrical furnace, because It is cheap It produces low cost product CaO content is less Of the better CaO/SiO₂ balance for slag formation It is cheap It produces low cost product CaO content is less Of the better CaO/SiO₂ balance for slag formation ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology In ammonia synthesis (N₂ + 3H₂ = 2NH₃), there is a decrease in total volume, hence to get high equilibrium conversion, the reaction should be carried out at Very high temperature High pressure Low pressure Atmospheric pressure; as the pressure has no effect on conversion Very high temperature High pressure Low pressure Atmospheric pressure; as the pressure has no effect on conversion ANSWER DOWNLOAD EXAMIANS APP
