How much water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution?
About 80ml of water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution.
If 2 percent glucose solution and 5 percent glucose solution are separated by a semipermiable menbrane flows from the 2 percent glucose solution to the 5 percent glucose solution?
Yes, during process of osmoses the solvent from higher concentration to lower concentration moves through semipermeable membrane, the 2% solution has lower concentration of solute therefore higher concentration of solvent.
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.
How many litres of 12 percent sodium hypochlorite solution are needed to make 100 Litre of 2 percent sodium hypochlorite solution?
(x L)((12%) = (100 L)(2%)x = 16.7 liters
How many chemical elements are liquids at room temperature?
Three. 35, 80, 112. The liquid status of 112 is still not certain. Two for sure, mercury and bromine.
Percents are often used to show the strength of solutions Which solution is stronger the 2 percent or the 3 percent?
A 3 percent solution is 1.5 times as strong as a 2 percent solution.
How much of a ten percent solution should be added to two cups of twenty percent solution to make a twelve percent solution?
2%
What happens when the bromine solution reacts with acetylyne?
The chemical equation is:C2H2 + 2 Br2 = C2Br2H4

Is a 2 percent salt solution hypertonic or hypotonic to a 4 percent salt solution?
hypotonic
How much water must be added to 40 ml of a 25 percent by weight solution to make a 2 percent by weight solution?
About 80ml of water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution.
A bag with a 2 percent solution is placed in a beaker that has a 10 percent solution is the solution in the bag hypotonic hypertonic or isotonic?
hypertonic
If 2 percent glucose solution and 5 percent glucose solution are separated by a semipermiable menbrane flows from the 2 percent glucose solution to the 5 percent glucose solution?
Yes, during process of osmoses the solvent from higher concentration to lower concentration moves through semipermeable membrane, the 2% solution has lower concentration of solute therefore higher concentration of solvent.
