What is the difference between a mixture and a solution?
2016年11月7日 · $\begingroup$ The gist is clear, but "mixture" is not so clearly defined, i think. Even "solution" does not have a clear-cut definition, if you try to avoid discussing it in terms of Gibbs free energy. Think of a solution of virus particles. Or polystyrene in an organic solvent. Interesting question, actually. $\endgroup$ –
Are all homogeneous mixtures just solutions? - Chemistry Stack …
2015年6月23日 · A solution is a liquid or solid phase containing more than one substance... So, the concept "solution" is reserved to solid and liquid phases. In gas phase: Air is an example of homogeneous mixture of nitrogen, oxygen, carbon dioxide and other gases present in air. It's obvious that air is not a solution.
Why is glass a mixture and not a solution?
2023年9月6日 · While studying mixtures and solutions, I read that glass is a mixture and not a solution. Then I searched over the Internet about it, but I got the same answer that it is a homogenous mixture. But nowhere did I find any meaningful answer about what the difference is in a homogeneous mixture and solution. People talked about particle size.
solubility - Suspension or Solution - Chemistry Stack Exchange
2017年4月3日 · $\begingroup$ If you point an intense light source to the surface of the liquid (either solution, colloïdal mixture) you may see if the light beam passes across the medium "without a trace", or if you observe a milky / foggy scattering that resembles more or less an illuminated rod (like above left hand example) if seen from the side. The ...
How to calculate the total concentration after mixing two …
Your new equation is correct because e.g. for the first solution, you have diluted 20ml to 50ml, so the new concentration will be 2/5 of the original concentration. Alternatively you could calculate the number of moles of each, add them and then divide by the total concentration to gives the concentration in mol/L or M.
Azeotropic mixtures and Raoult's Law - Chemistry Stack Exchange
2021年4月27日 · To understand why non - ideal mixtures form azeotropes, we need to understand what is ideal mixture. If you have a liquid mixture of two components A and B, ideal mixture is a mixture in which heterogeneous interactions (A - B) are the same as the average homogeneous (A - A and B - B).
Why are Colloids Heterogeneous? - Chemistry Stack Exchange
$\begingroup$ A solution of table salt (or any other low Mw solute) in water is surely homogeneous, because all inhomogeneieties have a similar (on a log scale) size and diffusion coefficient as the solvent molecules. For a polymer solution, you have to stretch this definition quite a bit already. For a colloidal solution even more. $\endgroup$ –
How is mole fraction of a solution different in vapour state vs in ...
2019年11月16日 · When you have a liquid mixture, there is a vapor phase that is made up of those same molecules in equilibrium with the liquid phase. There is no rule that says the moles will split 50/50 in the vapor and liquid phase or any other fraction.
aqueous solution - Long-term storage of Ascorbic Acid mixed with …
2017年5月29日 · Regarding the stability of storing the solid mixture vs. storing the solids separately, you are probably better off storing them separately until use. Both ascorbic acid and sodium ascorbate are susceptible to being oxidized by long-term exposure to air.
What is the difference between melting and dissolving?
Desolvation means removing the solvent from a solute-solvent mixture. (This can happen in crystallization, for example.) Solvation (which I think you're asking about) is the interaction of solvent particles with solute particles. Dissolving or dissolution is the process in which a solid, liquid, or gas forms a solution with a solvent.
