– Both salts of ammonium chloride & sodium chloride being readily soluble in water dissolves homogenously and sand being insoluble gets sedimented at bottom of soln. – Therefore, when this soln iz filtered, filtrate will contain aqueous soln of sodium chloride and ammonium chloride while residue contain sand.
Q. What happened to the water in the salt solution when heated?
For example, water can be separated from salt solution by simple distillation. When the solution is heated, the water evaporates. It is then cooled and condensed into a separate container. The salt does not evaporate and so it stays behind.

Q. How does temperature and solubility affect the dissolving speed of sugar and salt in water?
Changing temperature also affects the motion of the atoms, ions, or molecules of the substance and affects the interaction between water molecules and the particles of the substance. As the temperature increases, more and more sugar can be dissolved, but only slightly more salt can be dissolved.
Q. What are the three factors that affect the rate of dissolving?
The rate of dissolving depends on the surface area (solute in solid state), temperature and amount of stirring.
Q. What substance dissolves most?
water is called the “universal solvent” because it dissolves more substances than any other liquid.
Q. What types of solutes can water dissolve?
Sugar, sodium chloride, and hydrophilic proteins are all substances that dissolve in water. Oils, fats, and certain organic solvents do not dissolve in water because they are hydrophobic.
Q. Which substance would dissolve fastest in water?
Sugar
Q. What are the three factors that would make solid mixtures dissolve fast?
There are three factors that affect the rate of dissolution: (1) the surface area of the solute, (2) the temperature of the solvent, and (3) the amount of agitation that occurs when the solute and the solvent are mixed.
Q. Why does aspirin dissolve faster in hot water?
Think of it simply and basically: hot temperatures melts objects. The aspirin didn’t melt, but the hot water made it less solid, therefore it expanded. That expansion allowed more water to be exposed simultaneously to the same amount of aspirin, dissolving it faster.
Q. Which of the following has maximum solubility at low pH?
NH4Cl.
Q. Does the solubility of PbF2 change with pH?
Chemistry. Explain why the solubility of PbF2 is pH dependent, but the solubility of PbCl2 is not. So the solubility equilibrium of PbF2 is shifted to the right as the concentration of F^- ions is reduced by the protonation to form HF.
Q. Why alkanes are not soluble in water?
Alkanes are not soluble in water, which is highly polar. The two substances do not meet the criterion of solubility, namely, that “like dissolves like.” Water molecules are too strongly attracted to one another by hydrogen bonds to allow nonpolar alkanes to slip between them and dissolve.
