Which of the following aqueous solutions would have the lowest vapor pressure 0.15 m NaCl?
Answer and Explanation: The answer is c. 0.020 M MgCl2 M g C l 2 .
What is the vapor pressure of NaCl?
The vapor pressure lowerings of solutions of sodium chloride at 25 °C have been tabulated [3] and it can be shown that a solution 2.6185 m in sodium chloride has a vapor pressure 2.181 mm Hg lower than that of pure water at the same temperature.
Which of the following aqueous solution has highest vapour pressure?
Glucose in the equimolar mixture has higher vapour pressure.Hence, option A is correct.
Which of the following aqueous solutions would have the highest boiling point?
Thus, Na3PO4 has the highest boiling point.
Which of the following solution in water will have lowest vapour pressure?
1 Answer. Na3PO4 N a 3 P O 4 consist of maximum ions hence it show lowest vapour pressure.
What is the vapor pressure of CaCl2?
An aqueous CaCl2 solution has a vapor pressure of 81.6 mmHg at 50 degrees Celsius.
What is the vapor pressure of HCL?
603 psiaGeneral Information about Hydrogen Chloride Gas The boiling point of AHCl at one atmosphere pressure (14.7 psia, 760 mmHg) is -85°C (-121°F) and the vapor pressure of AHCl at ambient temperature of (20°C, 68°F) is 603 psia.
Does NaCl have a high vapor pressure?
All three of the sodium chloride solutions have lower vapor pressure than pure water at all temperatures. For example, at 90 degrees Celsius, pure water has the highest vapor pressure and solution C has the lowest vapor pressure.
Which of the following aqueous solutions will have maximum vapour pressure at constant temperature?
In solution, H2SO4 provides three ions. While NaCl provides two ions. Hence, vapour pressure of solution of NaCl is higher (as it gives less ions). Therefore, 1molalNaCl will have the maximum vapour pressure.
Which of the following has highest vapour pressure at room temperature?
Ether has the highest vapour pressure (i.e., lowest boilint point) at any temperature. The reason for its high vapour pressure is that the attraction is less between ether molecules than between water and alcohol molecules.
Which of the following solutions will have the maximum lowering of vapour pressure at 300 K?
The correct option is A The vapour pressure of water is 12.3 kPa at 300 K.
