pH measures acidity
Hydrogen-ion concentration changes logarithmically; neutralization depends on moles, not colours.
THE WORLD IS MADE OF REACTIONS
Don’t just watch chemistry.
Make it happen.
Change the concentration. Control a burette. Balance atoms. Speed up a reaction. Learn why every drop and every mole matters—with real calculations behind every colour and graph.

See what the numbers say
Tap a titration curve or a rate graph to change the measured point. Colours are illustrative; values come from the equation models.

CONNECT THE FIVE BIG IDEAS
Atoms are conserved
A balanced chemical equation has equal numbers of each element on both sides.
Titration measures amounts
The equivalence point follows reacting moles. It is not always pH 7 or exactly the indicator endpoint.
Rates respond to conditions
An Arrhenius temperature dependence and a reaction-rate law explain our illustrative A+B process.
Reagents run out
Stoichiometric ratios identify the limiting reagent, excess reactant, and maximum theoretical product.
