This project was preformed to supply Libretext authors with videos on General Chemistry topics which can be used to enhance their projects. Also, these videos are meant to act as a learning resource for all General Chemistry students . Video Topics Titration is the gradual interaction of an acid or base. We will be looking at how the pH of a solution changes during a strong acid / strong base titration. Important points: Starting point: Mol of added - OH = 0. The pH is completely determined by the molarity of the strong acid. Before the equivalence point: Mol of added - OH < Mol of H 3 O + . Subtract mol - OH from Mol H 3 O + to find the # Mol H 3 O + remaining. Divide by the V total to find {H 3 O + } Equivalence point: Mol of added - OH = Mol of H 3 O + . At the equivalence point of a strong acid / strong base titration the pH = 7. After the equivalence point: Mol of added - OH > Mol of H 3 O + . Subtract mol H 3 O + from Mol - OH to find the # Mol - OH remaining. Divide by the V total to find { - OH} Link to Video Introduction to the pH Curve for a Strong Acid/Strong Base Titration: https://youtu.be/kaObZtyKvsw Attribution Prof. Steven Farmer ( Sonoma State University )
