10 gm of silver nitrate solution is added to 10 gm of sodium chloride solution. What change in mass do you expect after the reaction and why?
No change in mass will take place because mass can neither be created nor destroyed in a chemical reaction as law of conservation of mass states.

The dissolution of ammonium chloride in water is endothermic process. What is the effect of temperature on its solubility ?
Since dissolution of NH4Cl in water is endothermic process, its solubility increases with rise in temperature (i.e., Le-Chatelier process).

why do HCl, HNO3, etc. show acidic character in aqueous solutions while solutions of compounds like C2H5OH and glucose do not show acidic character?
HCl, HNO3, etc., ionise in the aqueous solution to produce H+ ions. Hence, they show acidic character. Compounds like C2H5OH and glucose do not ionise in the aqueous solution to give...

What effect does the concentration of H+(aq) ions have on the acidic nature of the solution?
Water contains exactly the same number of H+ and OH- ions. Acidic solution contains more hydrogen ions than water. Higher the concentration of H+ ions in a solution, more acidic is the...
