Research question: To calculate the solubility of equal masses nitrates of four di-positive ions (Lead Nitrate, Barium Nitrate, Copper Nitrate & Ferrous Nitrate of 0.5 M concentration) in an equal volume of water and relate this to the ionic radius of the element and the molar mass of the nitrate chosen and hence comment on the intermolecular forces in each of these nitrates. + write mass
Justification of the research question: I was particularly interested in the difference in intermolecular forces of different nitrates and their relation with ionic radius. My imagination caught fire when I thought of this and thus I proceeded to conduct this experiment to find the relation between temperature of solubility, molar mass and ionic radius. Intermolecular forces had sparked interest in me from the very day it was begun to be taught. I have chosen all nitrate salts only as I wanted to compare my temperature results with the ionic radius of the metallic element in the compounds.
Background information: As previously taught, I know that the temperature of solubility of a salt will be higher if the molar mass of a substance is higher, as it will have more number of grams per mole, hence more amount of thermal energy will be needed to break the necessary intermolecular force for the salt to become soluble in the solvent. Secondly, I have chosen water as a solvent as I know that all nitrates are soluble in water. Thirdly, I am assuming that the temperature of solubility will be higher for a smaller ionic radius as the bond between the molecules of the compound will be much more (the electrons of the atom are more closely attracted to the nucleus, and hence in the bonding electron, the nucleus will have a greater pull as well, hence smaller ionic force, and hence more intermolecular force required). This is just an assumption and I will see if this assumption holds true or no after
