What are the advantages of liquid ammonia?
Advantages Of Liquid NH3 As a Solvent Solutions of alkali metals in liquid ammonia are strong reducing agents. These solutions are used extensively in synthetic inorganic and organic chemistry. 3. Ammonium salts (like ammonium nitrate) in liquid NH3 act as ammono acids and these are used in preparative chemistry.
Why liquid ammonia is a better solvent than water?
Due to less extensive hydrogen bonding, liquid NH3 is a better solvent for organic compounds which are more soluble than in water. 7. Due to its lower viscosity, liquid NH3 provides a better medium for the movement of ions in it. Liquid NH3 has higher specific heat than water.
What are the disadvantages of liquid ammonia?
Disadvantages Of Liquid NH3 As a Solvent The freezing point and melting point of liquid ammonia -77.7 and -33.40 are low and the liquid range is very small. Ammonia is a toxic compound. Due precautions need to be taken. It has to be worked in a closed system.
Why is liquid ammonia a good solvent?
Ammonia’s high boiling point relative to its heavier congeners is indicative of the formation of strong hydrogen bonding, which also results in a high heat of vaporization (23.35 kJ/mol). Liquid ammonia is a good solvent for organic molecules (e.g., esters, amines, benzene, and alcohols).
What are the advantages and disadvantages of liquid ammonia?
Liquid ammonia is a solvent than is less associated than water and could be a better solvent for some organic compounds. However, some of the disadvantages of liquid ammonia as a solvent are, It is not suitable for a high temperature and pressure study because its liquid range is -77 to -33 C.

What are the advantages and disadvantages of liquid ammonia over water as solvents?
What are the advantages and disadvantages of liquid SO2 as a solvent?
SO2 is a gas. Hence it can not be a solvent because the primary requirement for something to be a solvent is that it should be a liquid e.g. H2O, Acetone, Benzene. It is a better solvent for organic compounds because it is a non-polar solvent. Hence organic compounds can be better dissolved in non-polar solvents.
Which of the following is limitation of liq nh3?
they are toxic. Explanation: they contain ammonia a harmful compound. it’s freezing point is – 77.7 and melting point is -33.4 which is low.
What happens when ammonia mixes with water?
Ammonia gas dissolves easily in water to form ammonium hydroxide, a caustic solution and weak base.
