Which will have the lowest boiling point pure water 0.5 M NaCl aq 1.0 M NaCl aq or 2.0 M NaCl aq?
Pure water will have the lowest boiling point because it does not contain any solute particles to elevate the boiling point. As the concentration of NaCl increases, the boiling point also increases due to an increase in the number of solute particles that disrupt the formation of water vapor. Therefore, 0.5 M NaCl will have a higher boiling point than pure water, followed by 1.0 M NaCl, and finally 2.0 M NaCl will have the highest boiling point.
What is the effect of NaCl and CaCl2 on the boiling point of water?
Adding NaCl (table salt) or CaCl2 (calcium chloride) to water raises the boiling point of water. This is due to the phenomenon of boiling point elevation, where the presence of solute particles in water disrupts its ability to form vapor, requiring higher temperatures to boil.
What mass of NaCl would have to be dissolved in 1.000 kg of water to raise the boiling point by 2.00 degrees Celsius?
To calculate the mass of NaCl needed to raise the boiling point of 1.000 kg of water by 2.00 degrees Celsius, you would use the equation: ΔTb = i * Kf * m, where i is the van't Hoff factor (for NaCl, it is 2), Kf is the cryoscopic constant for water (1.86 °C kg/mol), ΔTb is the boiling point elevation (2.00 °C), and m is the molality of the solution (in mol/kg). Solve for 'm' first and then use that value to calculate the mass of NaCl needed.
Finding the normal freezing and boiling points of 21.2 g NaCl in 135mL of water?
The normal freezing point depression constant of water is 1.86°C/m. The normal boiling point elevation constant of water is 0.512°C/m. First, calculate the molality of the NaCl solution. Then use these constants to find the new freezing and boiling points of the solution.
How much would the boiling point of water increase if 4 mol of NaCl were addes to 1 kg of water?
The boiling point elevation constant for water is 0.512 °C/kg/mol. When 4 mol of NaCl are added to 1 kg of water, the increase in boiling point would be 4 * 0.512 = 2.048 °C.
What would the final boiling point of water be if 3 mol of NaCl were added to 1 kg of water (Kb 0.51 and degC(molkg) for water and i 2 for NaCl)?
103.06 degrees C
How much would the boiling point of water increase if 4 mol of NaCl were added to 1 kg of water?
4.08 degrees celcius
How much would the boiling point of water increased if 4 mol of NaCl were added to 1 Kg of water?
4.08 degrees celcius
Compute the boiling point elevation of a salt water solution that contains 3.40 g of NaCl dissolved in 148 ml of water?
The boiling point elevation of a solution can be calculated using the formula: ΔTb = i * Kf * m, where i is the van't Hoff factor, Kf is the cryoscopic constant for water (0.52 °C kg/mol), and m is the molality of the solution. First, calculate the molality of the NaCl solution using the given mass of NaCl and the molecular weight of NaCl to find the molality. Then, use this molality value in the formula along with the van't Hoff factor for NaCl in water (i = 2) to determine the boiling point elevation.
Boiling point in NaCl and KCl?
The boiling point of NaCl is 1 413 0C. The boiling point of potassium chloride is 1 420 0C.
What mass of nacl would have to be dissolved in 1.000kg of water to raise the boiling point by 2.00c?
To calculate the mass of NaCl needed to raise the boiling point of water by 2.00°C, you can use the formula ∆Tb = iKbm, where ∆Tb is the boiling point elevation, i is the van't Hoff factor (2 for NaCl), Kb is the ebullioscopic constant for water, and m is the molality of the solution. You first calculate the molality using the given data and then find the amount of NaCl needed.
What is NaCl boling point?
The boiling point of NaCl is 1413 oC.
