Which of the following has the highest boiling point 0.01 m Na2SO4?
Among the given alternatives, Na2SO4 will exhibit the highest boiling point since it will dissociate into 3 ions when dissolved in the solution.
Which has highest boiling point 0.1 m?
Answer : 0.1 M of NaCl has the higher boiling point. Explanation : Formula used for Elevation in boiling point : As per question, we conclude that the molality of the given solution are same. Now we have to calculate the Van’t Hoff factor for the given solutions. Hence, 0.1 M of NaCl has the higher boiling point.
Which of the following has highest boiling point 1.0 m Naoh?
Hence, 1.0 M Na2St4 has highest value of boiling point.
What is the boiling point of 0.1 M glucose?
The \[0.1\] molal aqueous solution of glucose boils at \[100.16^\circ {\text{ C}}\]. The boiling point of \[0.5\] molal aqueous solution of sucrose will be: A. \[500.80^\circ {\text{ C}}\].
Which has the highest boiling point?
Carbon has the highest melting point at 3823 K (3550 C) and Rhenium has the highest boiling point at 5870 K (5594 C).
Which of the following solution has the highest boiling point * 1 point 0.01 M glucose 0.01 M potassium sulphate 0.01 M potassium nitrate 0.01 M urea?
0.01 m will have highest boiling point. , i= 1 as it is a non electrolyte and does not dissociate. As the concentration is highest for 0.01 m , it will have highest boiling point.
Why Na2SO4 has a high boiling point?
Answer Expert Verified. Option (ii) 1.0 M Na2SO4 is correct because its molecular mass is highest among all that’s why its boiling point will be highest among four.
Which one of the following aqueous solutions has the highest boiling point?
Thus, Na3PO4 has the highest boiling point.
What is the lowest boiling point?
The element with the lowest boiling point is helium. Both the boiling points of rhenium and tungsten exceed 5000 K at standard pressure; because it is difficult to measure extreme temperatures precisely without bias, both have been cited in the literature as having the higher boiling point.
Which has higher boiling point 0.1 m NaCl or 0.1 m BaCl2?
Which will have higher boiling point, 0.1 M NaCl or 0.1 M BaCl2 solution In water and why ? Since both the salt solution have same concentration, therefore the salt which gives maximum number of ions will show higher boiling point. NaCl dissociate to give two ions while BaCl. Hence BaCl2 posses high boiling point.
Which metal has the highest boiling point?
The chemical element with the lowest boiling point is Helium and the element with the highest boiling point is Tungsten.
Which of the following has highest boiling point 1M glucose?
2M glucose has a higher boiling point than 1M glucose. Thus, option A is the correct answer.
Which has the lowest boiling point at 1 atm pressure?
The boiling point of a liquid at 1 atm is also known as the normal boiling point. It has been found that Helium has the lowest normal boiling point (−268.9 °C) because it has very weak intermolecular attractions.
How do you know which aqueous solution has the highest boiling point?
Multiply the original molality (m) of the solution by the number of particles formed when the solution dissolves. This will give you the total concentration of particles dissolved. Compare these values. The higher total concentration will result in a higher boiling point and a lower freezing point.
Why KCl has higher boiling point than glucose?
This is because KCl dissociates in water to give two ions (KCI→k4+Cl-), whereas glucose does not dissociate. Therefore, number of solute particles is greater in 0.1 m KCl as compared to 0.1 m glucose. Hence, elevation in boiling points in 0.1 m KCl will be higher and therefore, its boiling point will be higher.
Which has maximum boiling point 0.1 N NaCl?
0.1 M aqueous solution of ferric chloride has the highest boiling point. The dissociation of one molecule of ferric chloride gives the maximum number of ions (four ions) in the solution. Glucose is a non-electrolyte and it does not undergo dissociation.
What is the boiling point of glucose?
Predicted data is generated using the ACD/Labs Percepta Platform – PhysChem Module Density: 1.6±0.1 g/cm 3 Boiling Point: 527.1±50.0 °C at 760 mmHg Vapour Pressure: 0.0±3.1 mmHg at 25°C Enthalpy of Vaporization: 92.2±6.0 kJ/mol Flash Point: 286.7±26.6 °C.
What increases boiling point?
Compounds that can hydrogen bond will have higher boiling points than compounds that can only interact through London dispersion forces. An additional consideration for boiling points involves the vapor pressure and volatility of the compound. Typically, the more volatile a compound is, the lower its boiling point.
Why does boiling point increase across a period?
Across the period from left to right of the periodic table size of atoms decreases. As the size decreases the strength of van der Waals forces also decreases. If intermolecular forces increase, the vapor pressure of the compound decreases, and hence the boiling point of the compound increases.
Does HBR have a high boiling point?
-86.8°F (-66°C).
Which of the following solution has highest boiling point 1 point 0.01 M glucose 0.01 m K2SO4 0.01 M KNO3 0.01 M urea?
since number of solutes is maximum for K2SO4 that is 7 molecules hence maximum boiling point is for 0.1m K2SO4.
Which of the following has highest boiling point 0.01 M glucose?
0.01 M Na2SO4 B. 0.01 M KNO3 C. 0.015 M urea. D. 0.015 M glucose. Easy. Solution. Verified by Toppr. A. 0.01 M Na2SO4 △=i×kb×m. i×m of Na2SO4 is highest, hence its boiling point will also be highest. Na2SO4 i×m=3×0. 01=0. 03. KNO3 i×m=2×0. 01=0. 02. Urea i×m=1×0. 015=0. 015. Glucose i×m=1×0. 015=0. 015.
Which of the following 0.1 M aqueous solutions is likely to have the highest depression in freezing point?
(D) 0.01 m Na2SO4. Here the total number of ions is 3. So the depression in freezing point is 0.003. So here the lowest depression in freezing point has sucrose, hence it will have the highest freezing point.
Will Na2SO4 dissolve in water?
Sodium sulfate (also known as sodium sulphate or sulfate of soda) is the inorganic compound with formula Na2SO4 as well as several related hydrates. All forms are white solids that are highly soluble in water.
Does Na2SO4 form a precipitate?
You add 5 mL of sodium carbonate in tube 1. A precipitate, which looks like light blue specks of dust, forms. You carefully add the sodium sulphate solution into tube 2. No precipitate forms.
Is naso4 a salt?
Sodium sulfate (Na2SO4) is the sodium salt of sulfuric acid. Anhydrous sulfate is a white crystalline solid also known as the mineral thenardite, while the decahydrate Na2SO4. 10H2O has been known as Glauber’s salt or mirabilis.
