After we learned integration by parts in grade 11 AP calculus, we went on a tangent to apply this knowledge to trigonometric functions and substitutions. By then, we had acquired a fraction of the skills needed to integrate rational functions. With long division and partial fractions on our side, we can integrate problems of all shapes and sizes!
We performed titrations of hydrochloric acid with sodium hydroxide every day this week in grade 11 chemistry class. Using a pH indicator and burets, we measured how much of each reactant was required for a neutralization reaction by detecting the instant the indicator in the solution turned pink, showing that the reaction was complete.
Little did we know that our study of moles in grade 11 chemistry would not end with the unit test. After an in-depth look at moles, we started a new unit on solutions. We will be looking into topics such as solubility, pH, and concentration, applying our knowledge about moles in the many solutions we have yet to find.
