Chemistry

Enter the current chemistry slice through one bounded reaction branch and one bounded solutions-and-pH branch without leaving the same simulation-first product architecture.

Chemistry is still compact, but it is no longer just a pilot pair of pages. This subject now frames a rates-and-equilibrium branch alongside a solutions-and-pH branch so the chemistry slice feels like a real subject path instead of isolated catalog leaves.

Rates and Equilibrium

Not started

Start with successful collisions setting reaction rate, then reuse the same chemistry language inside a reversible system that re-balances after a disturbance.

Rates and Equilibrium

Use one compact chemistry branch where collision success explains reaction rate first, then the same particle language widens into reversible change and a new equilibrium mix.

Solutions and pH

Use one compact chemistry branch where concentration, dilution, acid-base balance, and pH all stay attached to the same bounded solution story.

Reaction Rate / Collision Theory

Keep one chemistry box visible so temperature, concentration, activation threshold, and catalysts can be read as changes in successful collisions instead of chemistry slogans.

Dynamic Equilibrium / Le Chatelier's Principle

Watch a reversible chemistry bench keep changing microscopically while the mixture settles toward a new balance after each disturbance.

Concentration and Dilution

Use one beaker to separate how concentration changes when you add solvent from how it changes when you add more solute.

Acid-Base / pH Intuition

Keep acid amount, base amount, water, and the pH strip visible together so acidity and basicity stay intuitive rather than memorized.
