![]() ![]() ![]() AgCl is an insoluble ionic compound, so the ions stay together in solution and fall to the bottom of the container as a precipitate. RbCl is a soluble ionic compound, so it exists as separate hydrated Rb + ions and hydrated Cl − ions in solution. C 6 H 12 O 6 is hydrated as described in part a. KF(aq) actually exists as separate hydrated K + ions and hydrated F − ions in solution: C 6 H 12 O 6 is a polar covalent molecule that is a nonelectrolyte. ![]() KF is a soluble ionic compound, so it is a strong electrolyte. Nonpolar solutes do not have permanent partial negative and partial positive ends nonpolar solutes are not stabilized in water and do not dissolve. These opposite charge attractions stabilize polar solutes in water. The oxygen end of water (the partial negative end of the polar water molecule) aligns with the partial positive end of the polar solute, whereas the hydrogens of water (the partial positive end of the polar water molecule) align with the partial negative end of the solute. Water is a polar molecule and dissolves other polar solutes readily. These are not full charges as in ionic compounds but are charges much smaller in magnitude. Polar molecules have a partial negative end and a partial positive end. Polar covalent compounds have an unequal sharing of electrons in bonds that results in unequal charge distribution in the overall molecule. Polarity is a term applied to covalent compounds. ![]()
