Could the addition of water for dissolving have been done first before the heating of the original mixer?
You heat water before you mix it because it increases the amount of solute that can be saturated into the solution.
Why is sodium carbonate added to solution before Benedicts test is performed?
Sodium carbonate is added to increase the pH of the solution.
What is the concentration of a solution in terms of solute per liter of solution?
The molarity of a solution is the number of moles of a solute per liter of its solution. The normality of a solution is the number of gram equivalent weight of a solute per liter of its solution. As I said before, and precisely, Molarity is moles of solute per VOLUME of solution!
How do you calculate non volatile matter percentage in a solution?
Non volatile matter = [(W2-W1)/V] x 100 where W2 :Weight of beaker [Before sample addition & evoporation] W1 :Weight of beaker [after sample evoporation] V : Volume of sample taken
Why honey does not dissolve in water?
Honey and water should be considered miscible. I.E. They should mix at any and amounts of honey and water, although in some cases honey may be supersaturated, and tend to crystallize when cooled independent of adding water. Since honey is very viscous, and heavier than water, it may be easiest to heat your solution to near the boiling point of water before mixing. Then you can cool it to the desired temperature after mixing. Try your solution in the microwave. You could also try just letting your water/honey mixture sit undisturbed at room temperature for a few days or weeks.

Why doesn't 5 tablespoons of sugar form any crystals in 250 ml of water?
In order to get any crystal-forming chemical to form crystals in solution, you need a "supersaturated" solution, which is made by heating water really hot and putting in more sugar than you can get to dissolve. Then you pour the hot sugar water off the leftovers in the bottom of the glass, and you're ready. The neat thing about this is, the amount of sugar you can put in water is temperature-dependent; the hotter the water, the more sugar it will hold, and as the temperature drops sugar will fall out of solution in crystalline form. Cool so far? Five tablespoons of sugar in 250ml water isn't enough to make a supersaturated solution. You didn't ask, but if you like rock candy it's easy to make. You need a supersaturated sugar solution and some string. Dunk the string in the sugar solution and let it dry. Then put it back in the sugar solution. Crystals will grow on the string. It's really fun to watch. Candy stores start with other rock candy--they tie a piece to the end of the string before they dunk it, so the string will hang down straight.
How do you get dissolve solid back from water?
You can prepare what is called a supersaturated solution. This is a solution that has more solute in it than "should" dissolve at a particular temperature.Make sure you have a clean and preferably new, unscratched container. Try not to add microscopic scratches to the container when stirring. A new unused glass beaker is ideal and stir with a plastic spatula.Prepare a saturated solution ie dissolve as much solute as you can into the liquid at a particular temperature.Heat the solution to a higher temperature. Your choice but 10 - 20 ºC is fine.Now carefully add more solute and stir. You do not want any solute particles sitting on the base so if you have some, either heat a little more or add a little more liquid.Cover, you do not want dust particles.Allow to cool slowly.You have a supersaturated solution that contains more solid solute than can be dissolved into the liquid. Congratulations.What can go wrong:It crystallises before it cools very much. Solution: do not be so ambitious with the change of temperature. It was too great a load for the solution to carry.One really cool thing to do next is to tap the side of the container, or to scratch the bottom of the beaker with a glass rod, or to drop a single tiny crystal into your supersaturated solution. Bingo, it will instantly drop the extra solute. Why? You provided it with nucleation sites for the crystals to form. It takes a little activation energy for crystals to form, you have to be careful not to provide it when the solution is being prepared. Just a scratch or even a knock will provide the nucleation site or the energy.
