What is the factor that is responsible for salts like NaCl to dissolve in water easily?(a) Decrease in entropy(b) Increase in entropy(c) Increase in enthalpy(d) Decrease in enthalpy |

Answer» Right choice is (b) Increase in entropy Easy explanation: As a salt such as NaCl dissolves, the Na^+ and Cl^– ions leaves the crystal lattice resulting in an increase in entropy(randomness) of the system which is largely responsible for the ease of dissolving salts such as NaCl in water. |
