which property of a distilled water solution will not be affected by adding 50 mL of CH3OH to 100.mL of the water solution at 25?
conductivity
mass
freezing point
boiling point
please help
The mass of the solution will change as a result of the newly added substance. Because of colligative properties, anytime something is added to solution, the freezing point is lowered and the boiling point is raised. Water does not conduct electricity on its own, and since CH3OH is not an acid or a base, it will not conduct electricity either, so that does not change.
The addition of CH3OH to an aqueous solution will cause the mass to increase. Of course. It will cause the freezing point to decrease. of course. It will cause the boiling point to increase. of course. What's left? Does CH3OH conduct electricity? Does pure water conduct electricity?
Well, well, well, it seems we have a chemistry question on our hands! Let's break it down, shall we?
When you add 50 mL of CH3OH (also known as methanol) to 100 mL of distilled water, which property remains unaffected? We have four options to consider: conductivity, mass, freezing point, and boiling point.
Now, let's rule out mass right off the bat. Adding more liquid to a solution will obviously affect its mass. So, sorry mass, you're outta the game!
Next up, let's talk about the freezing point. When you dissolve something in water, like good old CH3OH, it lowers the freezing point of the solution. So, say goodbye to freezing point, my friend.
What about boiling point? Well, adding more of the solute, in this case, methanol, generally raises the boiling point. So, boiling point can't hold its ground either.
That leaves us with conductivity. Adding an organic compound like methanol won't have a significant impact on the conductivity of the solution. So, conductivity remains unscathed!
To sum it up, my dear questioner, the property that won't be affected by adding 50 mL of CH3OH to the water solution is conductivity.
To determine which property of the distilled water solution will not be affected by adding 50 mL of CH3OH (methanol) to 100 mL of the water solution at 25°C, we can consider the properties of CH3OH.
1. Conductivity: Adding CH3OH to water would increase the conductivity of the solution because CH3OH is a polar compound that can participate in ionization and enhance the conductivity of the solution.
2. Mass: Adding CH3OH to water would increase the mass of the solution since CH3OH has a non-zero mass.
3. Freezing point: Adding a solute to a solvent typically lowers the freezing point of the solution. Therefore, adding CH3OH to water may affect the freezing point.
4. Boiling point: Adding a solute to a solvent can affect the boiling point of the solution. Therefore, adding CH3OH to water may affect the boiling point.
Out of the given options, the property that will not be affected by adding 50 mL of CH3OH to 100 mL of the water solution is the mass. The mass of the solution will increase due to the addition of CH3OH, but the addition of CH3OH will not directly impact the mass of the water itself.
To determine which property will not be affected by adding 50 mL of CH3OH (methanol) to 100 mL of water, we should consider the properties of the components.
1. Conductivity:
Both water and CH3OH are polar substances that can conduct electricity to some extent when dissolved in water. However, when methanol is added to water, it reduces the conductivity of the solution due to its lower level of ionization compared to water. Therefore, the conductivity property will be affected by the addition of CH3OH.
2. Mass:
Adding 50 mL of CH3OH to 100 mL of water will increase the total mass of the solution. Therefore, the mass property of the solution will be affected by the addition of CH3OH.
3. Freezing Point:
Methanol lowers the freezing point of water when it is added. This is because methanol disrupts the formation of hydrogen bonds between water molecules, preventing them from organizing into a solid lattice structure. As a result, the freezing point will be affected when CH3OH is added to the water solution.
4. Boiling Point:
Similarly to the freezing point, adding CH3OH to water will also affect the boiling point of the solution. Methanol has a lower boiling point than water, so the addition of CH3OH will lower the boiling point of the solution.
From the above analysis, we can conclude that the property which will not be affected by adding 50 mL of CH3OH to 100 mL of water is mass. The mass property will increase due to the addition of CH3OH, but it is not dependent on the specific properties of the added substance and doesn't change the fundamental nature of the water solution.
