Vant Hoff factor (i) is the ratio of the actual number of particles in solution to the number of formula units dissolved. The value of i depends upon the nature of solute and the solvent.
K4[Fe(CN)6] dissociates into four K+ ions and one [Fe(CN)6]4- ion in aqueous solution. Therefore, the value of i for K4[Fe(CN)6] is 5.
Let's analyze the given options one by one:
a) Al2(SO4)3
Al2(SO4)3 dissociates into two Al3+ ions and three SO42- ions in aqueous solution. Therefore, the value of i for Al2(SO4)3 is 5/2, which is not equal to 5. Hence, option A is incorrect.
b) AlCl3
AlCl3 dissociates into one Al3+ ion and three Cl- ions in aqueous solution. Therefore, the value of i for AlCl3 is 4, which is not equal to 5. Hence, option B is incorrect.
c) Al(NO3)3
Al(NO3)3 dissociates into one Al3+ ion and three NO3- ions in aqueous solution. Therefore, the value of i for Al(NO3)3 is 4, which is not equal to 5. Hence, option C is incorrect.
d) Al(OH)3
Al(OH)3 does not dissociate in aqueous solution. Therefore, the value of i for Al(OH)3 is 1, which is not equal to 5. Hence, option D is incorrect.
Therefore, the correct answer is option A, Al2(SO4)3, which dissociates into two Al3+ ions and three SO42- ions in aqueous solution, giving a value of i equal to 5.
K4[Fe(CN)6] dissociates into four K+ ions and one [Fe(CN)6]4- ion in aqueous solution. Therefore, the value of i for K4[Fe(CN)6] is 5.
Let's analyze the given options one by one:
a) Al2(SO4)3
Al2(SO4)3 dissociates into two Al3+ ions and three SO42- ions in aqueous solution. Therefore, the value of i for Al2(SO4)3 is 5/2, which is not equal to 5. Hence, option A is incorrect.
b) AlCl3
AlCl3 dissociates into one Al3+ ion and three Cl- ions in aqueous solution. Therefore, the value of i for AlCl3 is 4, which is not equal to 5. Hence, option B is incorrect.
c) Al(NO3)3
Al(NO3)3 dissociates into one Al3+ ion and three NO3- ions in aqueous solution. Therefore, the value of i for Al(NO3)3 is 4, which is not equal to 5. Hence, option C is incorrect.
d) Al(OH)3
Al(OH)3 does not dissociate in aqueous solution. Therefore, the value of i for Al(OH)3 is 1, which is not equal to 5. Hence, option D is incorrect.
Therefore, the correct answer is option A, Al2(SO4)3, which dissociates into two Al3+ ions and three SO42- ions in aqueous solution, giving a value of i equal to 5.
