Using particle theory to explain how a solution becomes saturated?
how will you use the particle theory to explain why a saturated solution at 30 degreecelsius can become dilute at 70degree Celsius
What happens to a solution when it is supersaturated?
A saturated solution can dissolve more when you increase its temperature and less when you decrease. When hot saturated solution is cooled to zero degrees Celsius, or beyond it the solubility of the solvent will decrease and precipitate until it forms a solid.A saturated solution is one that has reached its saturation level for a specific solute (what is dissolved in it). The saturation level depends on the temperature and different solutes have different saturation levels at different temperatures.When a saturated solution is cooled, one of two things can happen.If the temperature drop reduces the saturation level, the liquid will be supersaturated and some of the dissolved substance will precipitate out of the solution and you will eventually see particles or crystals floating on top or settling on bottom of the liquid.If the temperature drop is slow enough and the liquid is not disturbed, it may become supersaturated but retain the solute. The amount of solute will exceed the saturation level. Any disturbance can start the precipitation such as shaking or dropping something into the solution.
When the temperature in Celsius is doubled from 10 Celsius to 20 Celsius is the temperature doubled on the Fahrenheit scale?
No.
What is saturation humidity?
When air is saturated at 30 degrees celsius
What are Celsius and Fahrenheit?
temperature scalesBoth Celsius and Fahrenheit are forms of measuring the temperature.
Explain how you would prepare a saturated solution of potassium nitrate in water?
Add potassium nitrate to distilled water while stirring continuously; stop adding potassium nitrate once the chemical becomes saturated and stops dissolving in the water. Filter the solution into an evaporating dish and measure the temperature of the solution. Measure the temperature and carefully heat the solution under low heat. Weigh the potassium nitrate to determine its solubility. You should find that approximately 36 g of potassium nitrate can be dissolved in 100 ml of water at room temperature (25 degrees Celsius). santosh kumar.batchu santoshkumar@gmail.com
Will 110 g of KNO3 in 100 g of water at 40 degrees Celsius be saturated or unsaturated?
KNO3 140 g/100 g of water is a saturated solution at about 70 to 75 oC. The solubility change with temperature and it need to be stated for reference temperature. For standard room temperature, KNO3 is saturated at 38.3 g/ 100 g water.

What temperature does water with a salt solution boil at?
105 Celsius
What is the percent by weight of NaCl in a saturated solution of sodium chloride at 50 degree Celsius?
Min. 36,69 g NaCl in 100 g solution.
How does adding salt to water affect it freezing point?
Adding salt to water increases its density and lowers its freezing point. ---------------------- I've just completed a repeated experiment on the effects of salt and the freezing point of water. A saturated salt solution will not freeze at -15 degrees Celsius (my freezer temperature). At exactly -21.1 degrees Celsius the salt begins to crystallize out of the solution, along with the ice, until the solution completely freezes.
If a solution has a temperature of 355K what is the temperature in Degree Celsius?
zero Kelvin is -273.15 degrees C. therefore 355 - 273.15 = 81.85 degrees Celsius
What is the mass of NH4CL that must be dissolved in 200 grams of water 50 degree celsius to make a saturated solution?
104g

Over 9000!
If you put 50 grams of sodium chloride into 100 mL of water at 30 degrees celsius would you have a saturated solution unsaturated solution or a supersaturated solution?
Ammonium Nitrate! Fo sho doe.
Is potassium dichromate soluble in water?
The solubility of potassium dichromate in water is 4.9 g/100 ml (0°C)
