The Solution

Solution The businessman behind the desk, the scientist in the laboratory, the artist near the canvas, the mathematician will examine the symbols he placed on the blackboard - the ideas in their heads are very much in many respects It is different, but surprisingly similar. For example, businessmen need to think about the idea of ​​reducing costs and increasing the company's revenue. He must find creative ideas, old ideas, and a new combination of numbers that enables the company to profit and reduce costs.

A solution is a mixture of two or more substances evenly. This solution consists of two parts: solute and solvent. The solute is a dissolved substance, and the solvent is the main component of the solution. In the solution, since the solute and the solvent are uniformly mixed, they can not be easily distinguished from each other. The solution can exist at various stages (solid, liquid, gas). From the above example, we can understand the importance of the solution - the air we suck is a very important solution per se. The solution is available in our homes and various industries, which makes our life easier.

When we think about solutions, the first thing we think is water soluble substances. This is natural because water is a common solvent. However, the solution is not limited to the liquid phase. The solution can be in the gas phase - the air we breathe is a solution of the gas mixture. Solutions also exist in solid phase - Brass is a solid solution, a mixture of copper and zinc. The next section describes different types of solutions at different stages.

There are three different stages in solution, solute is divided into isotonicity, hypertonicity and hypotonicity. Isotonicity is when there is an amount of solute equal to the solution. As with equilibrium, there is no net change in the amount of water in both solutions. When the solute concentration of the solution is different, the solute with less solute becomes hypotonic, and the solute with high solute becomes hypertonic. Low permeability absorbs solute from hypertonic side and releases solute. These kinds of solutions have a final move. Molecule moves from hypotonic solution to hypertonic solution. The third way for substances to pass through cell membranes is to promote diffusion. This occurs when a special carrier protein passes through the membrane using active transport to carry dissolved solutes in water.

When a substance melts in another substance, it forms a solution. Molten substances are called solutes, and dissolved substances are called solvents. Both sugar and salt are relatively soluble in solution, but one dissolves faster than the other. In a simple experiment you can decide which will dissolve quickly. To do this you need to supply salt and sugar and measure the equivalent of the two substances. At least three solvents are also required. One of them is water. Recommended solvents include distilled vinegar and disinfectant alcohol. Be sure to set all three solvents to room temperature before proceeding with the experiment. Mark 3 cups with solvent name and salt word, then mark the other 3 cups with solvent name and word sugar
