Question about Solubility and temperature?

Question

How did the solubility of the NH4Cl vary with temperature? and Why does this variation occur?

Answer 1

Solubility, indeed increases with temperature. The particles of water have more energy and move a bit further apart. So there is more room for additional material to dissolve.

It is chemistry

Answer 2

NaCl(s) ? Na(aq)+ + Cl(aq)- -RTlnKeq = ?G = ?H – T?S ?H does no longer change significantly with a small change in T (~ninety 5°C) and for this reason has no impression on the shift of the equilibrium with T. ?S: earnings in entropy (+ve) from breaking apart the established xtl lattice, lack of entropy at the same time as H2O coordinates to cation and anion (about 16 H2O molecules are sure to Na+ in H2O). If ?S(soln) is +ve then heating the answer causes -T?S to change into extra detrimental and extra salt dissolves. it really is the most common situation. highly, besides the indisputable fact that, there are any form of salts (many times with large, highly-charged ions) the position ?S(soln) is -ve and heating the answer causes -T?S to change into extra +ve and the salt turns right into a lot less soluble. The solubility of NaCl is only about unchanged going from H2O at O°C to H2O at ~ninety 5°C (I have 35 to 37 g in accordance to 100g in my head) so ?S is purely incredibly +ve. human beings mistake the extra quick dissolution of salt in warm water as an advance in solubility, besides the indisputable fact that that's a kinetic no longer thermodynamic result. the speed unmarried-step reactions all advance with an advance in T (Arrhenius regulation) because of the upward push interior the collisions of molecules and ions that exceed the activation potential.. as well stirring (heating) the answer, grinding the crystals into an excellent powder will advance the floor area and for this reason will advance the speed of dissolution.

Answer 3

solubility increases when temperature increases..nuthing to do with chemicals
