How much water must be added to 300 liters of a solution so that its concentration change from 25 percent to 20 percent?
Well, isn't that a lovely little problem to solve? To decrease the concentration from 25% to 20%, we need to dilute the solution. Since the concentration is decreasing by 5%, we can calculate that we need to add 60 liters of water to the 300 liters of solution to achieve the desired concentration of 20%. Just like painting, a little change can make a big difference in creating the perfect mixture.
How much water added to convert a 10 percent solution to 02 percent solution?
add 4 parts water per part solution
Is a true solution always transparent?
It will be transparant if it is an aqueous solution. In other words, if water is the solvent then the solution will be transparant. The process of dissolvation involves the creation of intermolecular bonds between the solute particles and the water molecules. and once dissolved the solute particles remain surrounded by the water molecules. This situation keeps the particles spaced far enough apart to allow light to pass through the solution. If a liquid besides water is used, then it is possible to have a nontransparant solution, such as crude oil.
Is dilute hydrochloric acid a mixture?
Yes its solution in water is a mixture of hydrogen chloride and water.
A water solution whose pH is 10?
Is always basic.
