The right answer is b) 0.1 BaCl2 has the highest 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 of the following has higher boiling point 0.1 m NaCl or 0.1 M glucose?
Nacl has larger boiling point since :The aqueous NaCl solution has a higher concentration of particles. Moreover The vant hoff factor of Nacl is greater thn 1 while of glucose is 1.
Which of the following AQ Solutions will have the highest boiling point 0.1 m sucrose0 1’m Glucosed 1 nacl0 1 m cacl2?
0.1 molal solution of sodium chloride will have higher ΔTb and higher boiling point as well because it dissociates into ions. At the sametime, 0.1 molal glucose solution being a molecular solid will not dissociate into ions.
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.
Why bacl2 has high boiling point?
Elevation in boiling point is a colligative property which depends upon the number of atom, ion or molecule present in the solution. Since both the salt solution have same concentration, therefore the salt which gives maximum number of ions will show higher boiling point. Hence BaCl2 posses high boiling 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 one has highest boiling point 0.1 N Na2SO4?
Among the given alternatives, Na2SO4 will exhibit the highest boiling point since it will dissociate into 3 ions when dissolved in the solution.
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.
Which has higher boiling point 0.1 m NaCl or 0.1 m cacl2?
0.1 M CaCl_(2) has higher boiling point than 0.1 M NaCl. 0.1 M glucose exerts higher osmotic pressure than 0.08 M CH_(3)COOH (25% dissociated).
What is the boiling point of 0.1 M urea?
– So, the correct answer is option (B) 373.2 K .
Which has higher boiling point NaCl or cacl2?
So from everything I’ve learned, NaCl would be more effective for the melting, because calcium chloride dissociates into three ions and sodium chloride dissociates into two, so that would make the boiling point of water with calcium chloride higher.
Which solution has the highest boiling point?
Solution: 1 M AlC l 3 solution will have the highest boiling point is because colligative properties such as elevation in boiling point is directly proportional to number of particles in solutions and AlC l 3 produces highest number of particles or ions.
Which has maximum boiling point at one atmospheric pressure?
Van’t hoff is the number of ions a compound dissociates. So here we can see that the highest value of van’t hoff factor is of BaCl2 so it will have highest value of elevation constant and in continuation will have the highest boiling point among all. So, the correct answer is Option C.
Which has the lowest boiling point?
The chemical element with the lowest boiling point is Helium and the element with the highest boiling point is Tungsten. The unity used for the melting point is Celsius (C).
Which has higher boiling point NaCl or glucose?
Boiling point of NaCl wille higher than that of glucose . In Na+ and Cl– are bonded together by ionic bonding. While in glucose all the elements are bonded by covalent bonding.
Which one has the highest melting point?
The chemical element with the lowest melting point is Helium and the element with the highest melting point is Carbon.
What is the boiling point of 0.1 m CaCl2?
U5 x 10- The molal boiling point elevation of water is 0.512°C/m, therefore the boiling point of 0.1m CaCl2 solution in water is expected to be (1) 0.1536 °C (2) 99.8464 °C (3) 100.0512 °C (4) 100.1536 °C 0.1M NaCl and 1M CHCOOH are kont in.
Does KCl have a high boiling point?
2,588°F (1,420°C).
What is the pH of BaCl2?
The BaCl2-TEA pH 8.2 method is considered a good measure of the “potential” acidity in soils, whereas extraction by neutral, unbuffered salts (e.g., 1 N KCl) is more related to the immediate lime requirement (“active acidity”) and existing cation exchange capability (CEC) of the soil (Foth and Ellis 1988).
What is the boiling point of BaCl2?
2,840°F (1,560°C).
Which solution has lowest freezing point?
Remember, the greater the concentration of particles, the lower the freezing point will be. 0.1mCaI2 will have the lowest freezing point, followed by 0.1mNaCl, and the highest of the three solutions will be 0.1mC6H12O6, but all three of them will have a lower freezing point than pure water.
What is the freezing point of a 0.1 M solution of glucose?
The freezing point of 0.1 M solution of glucose is -1.860C.
What is the van’t Hoff factor for KCl?
The van’t Hoff factor is the number of particles into which the atom divides itself in the solution. It can also be defined as the number of ions formed by the compound in the solution, is known as van’t Hoff factor. Therefore, van’t Hoff factor is 2 for KCl.
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 of the following has highest boiling point 0.1 M urea?
FeCl3 has the highest boiling point. Because it is ionic and will have highest number of solute particles which will decrease the vapour pressure and increase the boiling point of the solution.
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.
