Question
A certain salt has a negative Enthalpy of Solution (i.e. Hsoln = –), and a positive Entropy of Solution (Ssoln = +). Upon increasing the temperature of the water solvent, you would expect: The solubility of the salt to increase The solubility of the salt to decrease The solubility to remain unchanged, as Hsoln & Ssoln have opposite signs The effect on the solubility cannot be determined
The solubility of the salt to increase
The solubility of the salt to decrease
The solubility to remain unchanged, as Hsoln & Ssoln have opposite signs
The effect on the solubility cannot be determined
The solubility of the salt to increase
The solubility of the salt to decrease
The solubility to remain unchanged, as Hsoln & Ssoln have opposite signs
The effect on the solubility cannot be determined
Explanation / Answer
answer : The solubility of the salt to decrease
explanation:
salt + H2O <--------------------------> salt solution , deltaH = -ve
here it is clealy mentioned that forward reaction is exothermic reaction . exothermic reactions favourable at lower temperatures. on increase in temperature the equilibrium will be shifted to backward direction. so solubility decreases.
