Hno3 has 2 dissociating ions whereas alno33 has 4 which, Ask an Expert

Academics

why, when 0.025 M HNO3 and 0.025 MAl(NO3)3 (noting that Al(NO3)3 solid is a hydrate - Al(NO3)3*9H2O) were diluted to 100 mL distilled water, their conductivities do not match the isomolar trend - the more ions dissociating, the more the solution will conduct?

my values: HNO3 - 7.80ms and Al(NO3)3 - 6.10ms

HNO3 has 2 dissociating ions whereas Al(NO3)3 has 4, which should result in a higher conductance value.

Would this have something to do with aluminum nitrate being paired with water as a solid?
