Hydrochloric acid is a strong corrosive acid. Its chemical formula is HCl. The other name for hydrochloric acid is hydrogen chloride or Muriatic acid. Hydrochloric acid is an inorganic chemical. HCl Forms when hydrogen chloride dissolves in water. Hydrochloric acid is a simple diatomic molecule, the chlorine atom and hydrogen connect over a ...
Hydrochloric acid is a clear solution with no colour. Moreover, it has also got a very pungent odour. Not only that, but it is also present in a lot of various concentrations in water. Therefore, the physical properties of it like the boiling point, melting point and density vary accordingly.
Hydrochloric acid reacts with a metal X to form a gas Y which burns with a 'pop' sound. Sodium hydroxide solution also reacts with the same metal X (on heating) to form the same gas Y. (a) Name X and Y (b) Write the chemical equation of the reaction of metal X with (i) hydrochloric acid, and (ii) sodium hydroxide solution.
Physical Properties of Salicylic Acid. Salicylic acid is a colourless, odourless and needle-shaped crystals at room temperature. The taste of salicylic acid is acrid. The boiling point and melting point of salicylic acid are 211oC and 315oC respectively. The salicylic acid molecule has two hydrogen bond donors and three hydrogen bond acceptors.
Solution. Verified by Toppr. Correct option is A) Physical properties of HCl acid such as boiling point and melting points, density and pH depend upon the concentration or molarity of HCl in the aqueous solution. They range from those of water at very low conc. approaching 0% HCl to values for fuming HCl over 40% HCl.
Hydrogen chloride gas is very soluble in water. It is dissolved in water to prepare hydrochloric acid by using an anti-suction device, as shown in the diagram. Very briefly explain, how this device prevents the suction of water into the flask, in which hydrogen chloride gas is produced.
In this procedure, we can manufacture the gas by the oxidation of hydrochloric acid in the presence of cuprous chloride at 723K and a pressure of 1 atmosphere. Physical Properties. Chlorine is a greenish-yellow gas. It has a pungent odour. It has a boiling point of 239.11K and a melting point of 171.6K. The gas is harmful to nature.
Why is pure acetic acid called glacial acetic acid? View Solution. Q 4. Consider the following statements: I. The melting point of pure ethanoic acid is 290 K. II. 5-8% solution of acetic acid in water is called glacial acetic acid. Now, choose the correct option. View Solution.
Otherwise, strong heating leads to decomposition. Decomposition produces ammonia and hydrochloric acid again. Properties of Ammonium Chloride. Physical Properties – Ammonium chloride is a white crystalline solid. It does not have a characteristic odour. The melting point of ammonium chloride is 338 0 Boiling point of this inorganic compound ...
And hence, water molecule takes part in extensive and more hydrogen bonding than Hydrofluoric acid. Water molecule through its extensive hydrogen bonding forms a bulky molecule and it is very difficult to break its bonds. A large amount of energy is required to break all its bonds. Thus H 2 O has a higher boiling point than H F.
