A .50 m solution of which solute has the largest van't hoff factor? a) CaCl2
b) K3PO4
c) LiCO3
d) NaNO3

b) K3PO4

Explanation:

Hello,

In this case, since the van't Hoff factor for ionizing solutes equals the number of ionized particles (ions), the van't Hoff factor for each salt is:

a) CaCl2 : i=3 since two chloride anions and one calcium cation are ionized.

b) K3PO4 : i=4 since one phosphate anion and three potassium cations are ionized.

c) Li2CO3 : i=3 since one carbonate anions and two lithium cations are ionized.

d) NaNO3: i=2 since one nitrate anion and one sodium cation are ionized.

Therefore, b) K3PO4 has the largest van't Hoff factor as more ions are formed during its dissolution.

Best regards.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
