Problem 148

You add an excess of solid MX in 250 g of water. You measure the freezing point and find it to be _ What is the Ksp of the solid? Assume the density of the solution is 1.0 g/cm3.

Step-by-Step Solution:
Step 1 of 3

General Chemistry 115 Week 6 Electron Geometry­ VSEPR; describes shape of electron pairs  Describes both lone pairs AND bonds around central atom Molecular Geometry­ Describes arrangement of nuclei  Includes geometry of ONLY bonds Bond Angles and Lone Pair Geometry: ­ Lone pairs take up more space than bonds ­ Distortion in bond angle is a result because the lone pair electrons are larger and repel the electrons in the bonds. The bonds can approach closer because bonds are smaller than non­bonding electrons ­ e.g. Methane (CH4) = 109.5 degrees bond angle Ammonia (NH3) = 107.5 degrees bond angle (one lone pair present) Water (H2O) = 104.5 degrees (2 lone pairs present) ­ Imagine molecular geometry as a s
