What do you need to dissolve a solid?
the answer to this one is, you cant dissolve a solid..like wood well you could with some chemicals that would eat away at the solid but if you mean putting it in some water and heat it up then no you can not.
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.
How do you prepare ppm solution from solid?
To prepare a parts per million (ppm) solution from a solid, you would first need to accurately measure the mass of the solid compound. Then, dissolve this solid in a known volume of solvent to make a specific concentration solution. Finally, calculate the ppm concentration by dividing the mass of the solid compound by the total mass of the solution and converting it to ppm.
What is the concentration of a solution expressed in moles of solute per 1000grams of solvent?
This concentration is known as molality, and it is expressed as moles of solute per kilogram of solvent. To convert from moles of solute per 1000 grams of solvent to molality, you need to convert the mass of the solvent from grams to kilograms before calculating the molality.
How can you prepare 1mm from 100mm NaNO2?
To prepare 1mm solution from 100mm NaNO2, you will need to dilute the stock solution by a factor of 100. You can do this by taking 1 mL of the 100mm solution and diluting it to a total volume of 100 mL with the appropriate solvent (such as water).

If I use a grill brush, do I need a cleaning solvent?
A cleaning solvent would help to get rid of the grit and dirt that are sealed on the metal grill by the temperatures of cooking on it. It is always a good idea to rinse completely before cooking on the grill again.
What simple rules do you need to know for buying storing and preparing meat?
keep at below 40 degrees F. rinse thoroughly in cold water
Why are pastas rinsed?
To prevent it from overcooking. Cold water will stop the cooking process. However, you need not rinse it if you want to serve the pasta immediately. -------------------------- Rinsing pasta removes the starch. If serving hot pasta, you want the starchy coating to remain in order to make your sauce stick. If you are making a cold pasta salad, you will want to rinse the pasta in cold water first.
Is ethanol the solvent or solute in gasoline?
Gasoline does not have a solvent, as it is commonly used, and it does not need a solvent. This is because gasoline is not a solid that needs dissolving, it is a liquid hydrocarbon already and is a solvent more than it can ever be a solvent.
What is the molality of a solid solution containing 0.125 g of chromium and 81.3 grams of iron?
To calculate the molality of the solid solution, you need to first find the moles of chromium and iron separately. Then, determine the total moles of solute (chromium) and solvent (iron). Finally, divide the moles of solute by the mass of the solvent (in kg) to get the molality. Molality (m) = moles of solute / mass of solvent (kg).
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.
Why do you need to carry out two types of filterations to achieve purification of solids in recrystallization work?
The compound that you are trying to recrystallize is soluble in hot solvent but relatively insoluble in cold solvent. You also must remove an impurity that is insoluble in hot and cold solvent. The first filtration (a hot filtration) is to filter out the impurity. The second filtration (a cold filtration) is to filter out the (hopefully pure) recrystallized compound.
How do you prepare ppm solution from solid?
To prepare a parts per million (ppm) solution from a solid, you would first need to accurately measure the mass of the solid compound. Then, dissolve this solid in a known volume of solvent to make a specific concentration solution. Finally, calculate the ppm concentration by dividing the mass of the solid compound by the total mass of the solution and converting it to ppm.
Why is iron considered a solvent?
because you need more solvent than solute, so you need more to steel i guess
What is the osmotic pressure of NaCl?
NaCl--table salt--is typically look at as the solid solute within a solution. The osmotic pressure you need is for the solvent which will need to be calculated I believe. The Van Hoff Factor for NaCl (1.9) is probably what you needed
Why was my hamster rock solid when you woke this morning?
it could be die in the night or mite be to cold for it so you mite need more bedding
