n Panama City, FL192.5 ppm320 ppmThe last result for the experiment was the water softening agents. The results of the softening tests showed that the ion exchange resin reduce water hardness more than the baking soda. The following table shows the difference.

The ion exchange resin works to soften by exchanging ‘soft’ ions for ‘hard’ ions. After both procedures with the water softening were completed, we did a EDTA titration test one the samples. Through the equation I used earlier (example equation 1), we found that the data proved the softener worked. By using the second equation (example equation 2) I found the total hardness of the water with the softener and I reported the data in Table 5 below. As you can see the baking soda did exactly what it was thought to do, it softened the sample water.

In conclusion, our hypothesis was proven false by the experiment. The reason for the fact that the tap waters pick up many impurities in their travels from being rainwater to coming out of the faucets. However, State College’s water purification system has been lately improved which is why the water here in State College is lower than the tap water in FL. Also, due to the fact that both the water from State College and Pittsburgh, PA comes from a near by water purifying company. Since there is so many residence in the areas of where the tap water was taken, the demand...
