__**Ksp Lab**__ **Purpose**: Determine the Ksp of Calcium Hydroxide **Conclusion:** Using the data collected from the lab, we were able to figure out the moles of OH-. We took the concentration of the H+(.05) and multiplied it by the volume of the equivalence point (.001145L) which gave us 0.000573 moles of OH-. Next we calculated the [OH-] by taking the moles of OH- (.000573) and dividing it by the volume of the tested calcium hydroxide (.015L), which gave us 0.0382. After that, we calculated the [Ca+2]. We calculated the Ksp for calcium hydroxide by taking the [Ca+2] and multiplying it with [OH-] to get 2.7*10^-5. The accepted value for the Ksp for calcium hydroxide is 5.5*10^-6, which means that there were a few things that had to have gone wrong. Some possible sources that might have caused the experimental error are not precisely measuring out things, miscounting the amount of HCl added, and not checking the equivalence point at the right times. **__The Effect of Concentration on Solubility Lab__**
 * Purpose**: The purpose of this lab is to study how increasing the concentration of an ionic compound will affect its conductivity.


 * Conclusion **: In Conclusion, you can see that the more drops you add to a solution, the more conductive it will be. You can also see that the solution that was affected the most by adding more drops was the AlCl3, followed by CaCl2, and finally NaCl. This is due to the amount of ions that each of the solutions have. AlCl3 has 4 ions, CaCl2 has 3, and NaCl has 2. The ions help make the solution become more conductive because ions pass electricity from one to the next through the solution. Knowing this, the amount (drops) that we put into the water directly affect the conductivity.
