Curated OER
Introduction to Neutraliization
Students explore acids and bases and the process of neutralization.T hey practice volume measurements and observe the neutralization of an acid
directly through bubble formation and indirectly through indicator color changes.
Curated OER
Invisible Ink
Students wxplore acids and indicators by watching a demostration in which "magic" ink appears. They duplicate the demonstration by writing magic messages using phenolphthalein solution and painting the message with vinegar to show it.
