Discussion of Results and Scientific Explanation To achieve the goal of determining an unknown acid or base, anion and cation test were performed. These tests allowed for the components of the solutions to be identified, therefore, achieve the second goal. The pH was also used in to help find the identity of the unknown solutions and it was used to draw conclusions about the solutions. Dilutions were used to help understand the different behaviors of different concentrations. Household items were used to help apply basic theories about acids and bases such as pH. The titration curves were evaluated to help determine which indicator needed to be used for the indicator titration.
Anions are ions that have more electrons than protons, therefore, …show more content…
The titration was performed so that the solutions could be neutralized. Titration curves can be used to evaluate the pH when a titrant is added. You can calculate the pH from the curve by first determining how much titrant will be added. You can then evaluate the intersection between that volume and the graph. This intersection will tell you the pH at that volume. All titration curves should begin with slow movement as the titrant is added. It should then increase in speed before and then it should slow down again. This format is seen because at the start of the titration the titrant is added which slowly causes the pH to change. Then when the solution reaches neutralization the curve quickly changes. This point of change is called the equivalence point and it is where the hydrogen ions is equal to the hydroxide ions. The point commonly occurs around the pH of seven. After the equivalence point is reached, the solution will then start to be concentrated with hydrogen or hydroxide ions depending on the starting and titrant solutions. If the titrant is acidic, the solution will decrease in pH after the equivalence point until it reaches the pH of the titrant. The same theory is followed when the titrant is basic, except the pH of the solution increases instead of
