To determine if a solution is saturated or unsaturated, we need to compare the actual solubility of the solute at the given temperature to the amount of solute dissolved in the solution. At 40 degrees Celsius, the solubility of KNO3 in water is approximately 80 g/100 g water. Since you have 110 g of KNO3 in 100 g of water, the solution is supersaturated because it contains more solute than it can normally hold at that temperature.

What is the different between saturated and unsaturated?

Saturated hydrocarbon does not decolourise bromine water while unsaturated hydrocarbon decolourize it.


Is the mixture of sugar in water saturated or unsaturated?

Whether a sugar-water mixture is saturated or unsaturated depends on the amount of sugar that has been dissolved in the water. If no more sugar can be dissolved in the water at a given temperature, the solution is saturated; if more sugar can be dissolved, it is unsaturated.


Simple distinguished test between saturated and unsaturated compounds?

One simple test to distinguish between saturated and unsaturated compounds is the bromine water test. Saturated compounds do not react with bromine water (no color change), whereas unsaturated compounds will decolorize the bromine water due to addition of bromine across the double bond in the unsaturated compound.


Is saltwater solution saturated or unsaturated?

From your question it is impossible to tell. A salt-water solution can be unsaturated or saturated depending on how much salt was added.


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.


What is a solution that is far from being saturated called?

water


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.


Is dripping saturated or unsaturated?

Saturated means more than it can hold so dripping wet would be saturated with water.


Which is more dense air saturated with water vapor or air unsaturated with water vapor?

Saturated air is more dense.


What is an example of something unsaturated?

Dry stuff. It's not saturated with water...


How are the saturated zone and unsaturated zone alike?

Both the saturated zone and unsaturated zone are parts of the subsurface that store groundwater. In the saturated zone, all pores are filled with water, while in the unsaturated zone, pores contain both air and water. Both zones are important for groundwater flow and storage.


What are the reagents used distingush saturated and unsaturated organic compounds?

Basically there are many tests which is usually practiced to distinguish saturated Organic compounds from the unsaturated ones. But two of them are the most common: 1. Bromine water test. 2. Bayer's test. Basically Bromine water is red in color, so when an unsaturated compound (Alkene or Alkyne) is treated with it. The Bromine water get decolourized, on the other side the color is not changed when treated with saturated compound. In the Bayer's test KMnO4 solution is used, the unsaturated compound vanish its pink color while the saturated compounds do not.
