How do you make 2ppm solution of NaF?
To prepare a 2 ppm (parts per million) solution of sodium fluoride (NaF), dissolve 2 milligrams of NaF in enough distilled water to make a total volume of 1 liter. First, accurately weigh 2 mg of NaF using a balance, then add it to a volumetric flask or a clean container, and fill with distilled water up to the 1-liter mark. Mix thoroughly to ensure the NaF is completely dissolved.
Do all solid particles dissolve in water?
No, not all solid particles dissolve in water. The solubility of a solid in water depends on its specific properties, such as molecular structure and interactions with water molecules. Some solids are insoluble in water, meaning they do not dissolve and remain as solid particles.
What solid substance will dissolve instantly in cold water. The substance will need to be able to hold about 200g of weight and instantly dissolve in cold water?
Solid oxygen. Though it might make one hell of a bang ;) Formed at -218 Celcius, or 54 Kelvin.
If a solid can dissovle in water it is called?
Yes, This solid is called a solute.
What happen to liquid in water?
When a solid is placed in water, it will dissolve if the attractive forces between the water molecules and the solid molecules are stronger than the forces holding the solid molecules together. If the solid does not dissolve, it may remain suspended in the water as a suspension or sink to the bottom as a sediment.
Why does solid dissolve in water?
Solid NaF is a highly polar (in fact ionic) material and thus will easily dissolve in a high polarity solvent such as water. The water, solvates (hydrates) each ion whether F- or Na+ .
Where does a solid dissolve?
In the water
A solid that does dissolve in water is called?
This solid is called a solute.
Does salt dissolve candy?
Salt is a solid; water can dissolve candies.
How many grams of sodium fluoride are needed to prepare a 0.400m NaF solution that contains 750g of water?
To prepare a 0.400m NaF solution, you need to dissolve 0.400 moles of NaF per liter of solution. With 750g of water, you have about 0.416 L of water. To calculate the grams of NaF needed, multiply the molarity by the volume of solution in liters, then multiply by the molar mass of NaF (sodium fluoride: 41.99 g/mol). So, you would need about 6.991 grams of NaF.

Why isn't that the solids doesn't dissolve in water?
because the solid is not a water
Will all solids desolve on water?
No, lead is a solid that won't dissolve in water, though solid ice will.
Does coal dissolve in water?
No, coal does not dissolve in water. Coal is a solid, carbon-rich material that does not have the ability to dissolve in water as it lacks the necessary chemical properties for dissolution.
Do all SOLID partcles dissolved in WATER. why?
No. Only solid stuff with special chemicals in them dissolve, like sugar and salt. Notice that things only dissolve in warm water, and never ice water. Example: If you put sand in water, it doesn't dissolve.
What happens if solids are soluble in water?
They will dissolve in the water and form a solution. The amount that will dissolve depends on the solubility of the solid and the temperature.
