Tutoring chemistry, terms are important. The tutor distinguishes amphoteric and amphiprotic. If a species is amphoteric, it can act either as an acid or a base, depending on the context. A term that sounds somewhat similar – amphiprotic – means …
Tutoring physics and chemistry, scientific notation is important. The tutor mentions hints about it for users of the beloved Casio fx-260Solar. Over the years, the Casio fx-260Solar has been a faithful friend. It’s affordable, yet fully functional for a science …

Self-tutoring about terms in chemistry: the tutor mentions the term thixotropic. When a fluid is thixotropic, it gets thinner when agitated, but more settled when left alone. I wasn’t aware of this property until I experienced it with fluid film, …
Tutoring chemistry, one encounters terms. The tutor mentions the idea of dentates with ligands. As I mention in my post from Jan 23, 2022, a ligand is a molecule, or perhaps an ion, one or more of which surround a …
Tutoring chemistry, there are fundamental laws. The tutor mentions conservation of mass. The Law of Conservation of Mass states that the total mass of the reactants – or inputs – of a reaction will equal the total mass of the …
Tutoring chemistry, definitions and the ideas behind them are important. The tutor compares suspension with dispersion. Suspensions and dispersions are both mixtures in which one phase contains and separates a less numerous one. One difference between them is that with …
Tutoring chemistry, mixtures are important. The tutor mentions the idea of a colloid. A colloid is a mixture with two phases: the dispersing medium and the dispersed constituent. Some examples are foam, mayonnaise, fog, cheese, and mud. One key characteristic …
Tutoring chemistry, definitions can be intriguing. The tutor mentions two with an idea of how to distinguish them. Let’s imagine we agree that “stable” means “it won’t change on its own.” What does metastable mean, then? A book on a …
