Does water boil faster with dissolved solids?
No, water does not boil faster with dissolved solids. In fact, the presence of dissolved solids increases the boiling point of water, a phenomenon known as boiling point elevation. This means that water with dissolved solids will require a higher temperature to reach its boiling point compared to pure water. Therefore, the boiling process may take longer when solids are present.
How does the presence of dissolved sodium chloride affect the boiling and freezing point of water?
Dissolved solute (NaCl, salt) will raise the boiling point and lower the freezing point of water. This is known as a colligative property.
What is the change in the boiling point and freezing point of 500 grams of water if 45 grams of glucose C6H12O6 were dissolved in it?
This quantity is equivalent to 90 g glucose / kg water = 0.50 mole particles of solute / kg water, so with a 'molar cryoscopic constant' for water of -1.86 oC/kgthis lowers the freezing point to -0.93 oC.
What 2 factors affect the boiling point of water?
Pressure & Temperature :) Apex
What are the boiling and melting point's of salty water?
That depends on how much salt is dissolved in the water. Generally, the boiling point will be higher than for pure water, and the melting point will be lower than for pure water.
What is the boiling point of water glucose?
The boiling point of water is 100 degrees Celsius. Glucose, on the other hand, does not have a fixed boiling point because it decomposes before reaching a boiling point.

No, water does not boil faster with dissolved solids. In fact, the presence of dissolved solids increases the boiling point of water, a phenomenon known as boiling point elevation.

Does changing the amount of sugar affect the boiling point of water?
Yes. Dissolved sugar increase the boiling point.

What is the most boiling point of water?
The Boiling point of water is 100oC. It may change just 1-2 degrees due to the impurities dissolved in it.
What are physical changes of antifreeze when dissolved in water?
will change the boiling and freezing point of the water
What are the boiling and melting point's of salty water?
That depends on how much salt is dissolved in the water. Generally, the boiling point will be higher than for pure water, and the melting point will be lower than for pure water.
What happens to the boiling point of water if something is dissolved in it?
The boiling point of water increases when a solute is dissolved in it. This is because the presence of a solute disrupts the hydrogen bonding between water molecules, making it harder for them to break free and vaporize.
Why does the KCI solution have the higher boiling point if in a experiment 1 mol KCLid dissolved in a 1.4 kg sample of waater the 1mol glucose ids dissolved i another 1.4kg sample of water?
The KCl solution has a higher boiling point than the glucose solution due to the presence of ions. KCl dissociates into potassium (K⁺) and chloride (Cl⁻) ions in solution, effectively increasing the number of solute particles (colligative properties). In contrast, glucose does not dissociate and remains as intact molecules, resulting in fewer solute particles. This increase in particle concentration in the KCl solution elevates its boiling point through boiling point elevation.
What is the effect of impurities on the melting point of ice and the boiling point of water?
The freezing point of water decreases when the number of dissolved molecules (or better particles) in the solvent increases. This is called freezing point depression and you can easily find the relation between the quantity of particles dissolved and the freezing point on Wikipedia.
