How many grams of potassium chlorate are needed to make a saturated solution in 200 grams of water at 60 degrees C?
At 60 degrees Celsius, the solubility of potassium chlorate (KClO₃) in water is approximately 7.2 grams per 100 grams of water. To create a saturated solution in 200 grams of water, you would need about 14.4 grams of potassium chlorate (7.2 g/100 g water x 200 g water = 14.4 g KClO₃). Thus, 14.4 grams of potassium chlorate would be required for saturation at this temperature.
What else can I help you with?
If a solution is saturated at 20 degrees will it be saturated at 25 degrees?
No, the solubility of most substances increases with temperature. Therefore, if a solution is saturated at 20 degrees, it will likely be unsaturated at 25 degrees because more solute can dissolve at the higher temperature.
What do you expect to observe when a solution of potassium nitrate saturated at 343k or 70 degree celsius is cooled to room temperature?
Well, isn't that just a happy little question! When you cool a saturated solution of potassium nitrate from 70 degrees Celsius to room temperature, you can expect to see some of the potassium nitrate start to come out of the solution and form crystals. It's like nature's way of showing us how beautiful and orderly things can be when they slow down and cool off. Just like painting a serene winter scene, the crystals will slowly appear and bring a sense of peace and tranquility to the solution.
Ken had a beaker containing 54g of potassium chloride dissolved in 100cm3 of water at 90 degrees. he cooled the solution to 40 degrees. what would he see as the solutio cooled to 40 degrees?
As Ken cooled the potassium chloride solution from 90 degrees to 40 degrees, he would likely observe crystallization occurring. This is because the solubility of potassium chloride decreases with temperature, leading to the formation of solid crystals as the solution becomes supersaturated. He may see white crystals forming at the bottom of the beaker or floating in the solution as the solute precipitates out.
What solution which will not freeze at 0 degrees Celsius?
One solution that will not freeze at 0 degrees Celsius is a saturated salt solution, such as a solution of sodium chloride (table salt) in water. The addition of salt lowers the freezing point of water, preventing it from freezing at 0 degrees Celsius.
How much cerium sulfate is needed to make a saturated solution in 100 ml of water at 30 degrees C?
You need min. 5,63 g cerium sulfate.
If 50 grams of water satured with potassium chlorate 23 Celsius is slowly evaporated to dryness how many grams of the dry salt will be recovered?
If 50 grams of water saturated with potassium chlorate at 23 degrees Celsius is slowly evaporated to dryness, approximately 6.5 grams of the dry salt (potassium chlorate) would be recovered. This is based on the solubility of potassium chlorate in water at that temperature.
How many grams of potassium chlorate must be added to 1 liter of water to produce a saturated solution at 50 degree celsius?
At 50 degrees on the solubility curve KClO3 should be saturated at 21g per 100g of water. Knowing this the one liter given to you in the question can be written as 1,000 ml or 1,000g of H2O since the density of water is 1g/ml. Set up an equation: 21g KCLO3/ 100g Water = x/ 1000g water x=210g Answer: 210g KClO3
What is the mass of potassium chlorate that will dissolve in 50 g of water at 20 degrees Celsius?
Aproximately 4 grams of potassium chlorate will dissolve in 50 g of water at 20 degrees celsius.
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?
At 40 degrees Celsius, 110 g of KNO3 is more than the solubility limit of KNO3 in 100 g of water. Therefore, the solution will be saturated because it has dissolved the maximum amount of KNO3 that it can hold at that temperature.

What is the percent by weight of NaCl in a saturated solution of sodium chloride at 50 degree Celsius?
The percent by weight of NaCl in a saturated solution at 50 degrees Celsius is approximately 26.3%. This means that in every 100 grams of the solution, 26.3 grams is NaCl.
What type of solution is it if 25g KCl are dissolved in 100g of water at 30 degrees celsius?
This would be considered a saturated solution if all 25g of KCl are completely dissolved in the 100g of water at 30 degrees Celsius.
Explain how you would prepare a saturated solution of sugar in water?
No. If a saturated solution is heated, it will no longer be fully saturated. Water at 25°C will be saturated with sugar at a ratio of 100 grams of sugar to 100 grams of water. At 50°C it would take 130 grams of sugar to reach saturation. See this link for a full explanation: http://www.scienceclarified.com/Ro-Sp/Solution.html
