What amount of water is added in an aqueous solution of 5000 ml having concentration 1.5 M to prepare 0.5 M solution ?
$ M_1 V_1 = M_2 V_2 5000 ml = 5 lit $ $ 1.5 \times 5 = 0.5 \times V_2 $ $ \therefore V_2 = 15 lit $ $ \therefore Amount of water added = 15 - 5 = 10 lit $
On Which factors, the solubility of gaseous solute in liquid depends ?
The solubility of a gaseous solute in a liquid depends on temperature, pressure of the gas, and the nature of the gaseous solute and solvent. All these factors play a role in determining the solubility.
At 293 K temperature, if partial pressure of all given gases are same, then, which of the following gas possesses maximum solubility in water ?
According to Henry's law constant,' for a given external pressure of a gas, its solubility is inversely proportional to Henry's law constant,i.e, higher the value of , lower the solubility.
Henry law constant for helium is highest and lowest for oxygen. The order is :
Hence, option D is correct.
At 298 K temperature, if partial pressure of all given gases are same, then, which of the following gas possesses least solubility in water ?
Which one of the following salts will have the same value of van't hoff factor (i) as that of K4[Fe(CN)6]?
The van't Hoff factor (i) for K₄[Fe(CN)₆] is 5, as it dissociates to form 5 ions in solution. The salt Al₂(SO₄)₃ also has a van't Hoff factor of 5, as it dissociates to form 1 Al₂(SO₄)₃ and 3 SO₄²⻠ions, making a total of 5 ions.
At 293 K temperature, if partial pressure of all given gases are same, then, which of the following is the correct descending order of solubility of gases in water ?
At 293 K temperature, for solubility of all given gases, in water, which gas possesses higher value of KH ?
At 293 K temperature, for solubility of all given gases, in water, which gas possesses lower value of KH ?
At 298 K temperature, for solubility of all given gases, which of the following is the correct ascending order of values of Henry’s constant ?
At 293 K temperature, for solubility of all given gases, which of the following is the correct descending order of values of Henry’s constant ?
