Please I asked 3 times and I don't know what else to do??

Question

Please if you know chemistry answer this question

What specific factors favor the dissolving of sodium chloride in water?

Explain please

is it the size of particles being dissolved in the solvent or is it the amount of solute already dissolved in water or is it the temperature of the solvent or is it the stirring of the solution.

Answer 1

First thing is the solubility of the solute in the solvent (in your case salt in water).  If the solute is not soluable in the solvent, then no amount of stirring or temperature or particle size or time will create any dissolution.  You also need to keep two ideas separate: what is the maximum solubilty and how fast will the concentration increase to the max limit.

Typically (but not always) when things are soluable, they  become more soluable as the temperature increases, the max soluability increases.  It is also true that higher temperature also increases the speed at which things dissolve.  

Stirring and particle size will affect how fast the salt dissolves but neither of these will increase the max solubility limit (unless you stir so fast that you raise the temperature).

If you add more salt than the water can hold (more than the max soluability) then no amount of time or stirring will cause the "extra" salt to dissolve.  If you heat the water up and get it saturated (to the limit) and then the water cools off, salt that was in solution will precipitate out.

hope this helps.

Answer 2

mixing = stirring or shaking causes the particles to seperate form one another and spread out more quickly amoung the solvent particles

heating = causes particles to move more quickly.  The colvent particles can seperate the solute particles and spread them out more quickly.

crushing = the solute increases the amount of contact between the solute and the solvent.  THe particles of solute mix with the solent more quickly.

This holds true to any solid dissolving in a liquid..meaning it will work for salt dissolving in water....So it is mixing, heating, and crushing!

Answer 3

Stirring it helps it dissolve faster, and the amount of the solvent doesn't really matter only if you need to dissolve more.  Heating it helps, for you can dissolve more as the saturation raises with the tempurature.  Stirring it helps dissolve faster and heating (not boiling the water) will make the process even quicker

Answer 4

O.K. Here goes: The NaCl or salt, is the solute that dissolves in the solvent H20 or water.

Tempurature is a factor.Salt water freezes more rapidly that plain water.The salt in ice water lowers it's point of freezing so the water is still liquid. (Like when you pour salt on winter ice). Size of the particles are a factor. Think of a lump of salt in a beaker of water. It would take longer for that to dissolve than the small particles in table salt.

Before dissolving, there is a higher degree (and larger particles)of salt particles than those of water.After dissolving, the particles of salt decrease in amount and size, and the water particles increase in amount.

I hope this helps. I am not a chemistry major or teacher, but I just had this material in a class.

Answer 5

strirring actually helps to dissolve NaCl in water faster. it generally depends on the solute and solvent compatibility
