Use one compact chemistry branch where concentration, dilution, acid-base balance, and pH all stay attached to the same bounded solution story.
This topic broadens Chemistry beyond the rates-and-equilibrium pilot without inventing a giant chemistry engine. Concentration and Dilution keeps amount and volume visible together in one beaker, and Acid-Base / pH Intuition reuses that same solution-first language while acid amount, base amount, water, and the pH strip move together.
Best first concepts
The topic page keeps these starts in their own compact row so the first screen is about orientation and next action, not stacked feature cards.
Use one beaker to separate how concentration changes when you add solvent from how it changes when you add more solute.
How crowded the solution is
Strong first stop for getting into this topic without scanning the whole library.
Keep acid amount, base amount, water, and the pH strip visible together so acidity and basicity stay intuitive rather than memorized.
Acid-base balance
Strong first stop for getting into this topic without scanning the whole library.
Related guided tracks
These tracks stay tied to the same shared concept pages and progress model. They are surfaced here either because the authored path meaningfully overlaps this topic page or because the topic catalog marks the track as useful preparation for this branch.
Start with concentration and dilution in one beaker, then reuse that same solution language to read acid-base balance and pH.
Track progress
0 / 4 moments complete
0 / 2 concepts and 0 / 2 checkpoints cleared.
Concentration and Dilution opens this track and sets up the rest of the path.
Specific learning goals
These goal cards stay authored and transparent. They reuse the current topic page, starter tracks, guided collections, concept bundles, and progress cues instead of adding a separate recommendation system on top of this branch.
Use the solutions-and-pH topic route, the new starter track, and the rates-and-equilibrium topic page so Chemistry feels broader without becoming sprawling.

Grouped concept overview
Each group is authored in the topic catalog, but the actual concepts, progress badges, and track cues still come from the canonical concept metadata and shared progress model.
Group 01
Start with one beaker where the amount of solute and the amount of liquid can be changed separately, so dilution stays honest.
Use one beaker to separate how concentration changes when you add solvent from how it changes when you add more solute.

Group 02
Carry the same solution language into a pH story where acid character, base character, and water all push on the same bounded system.
Keep acid amount, base amount, water, and the pH strip visible together so acidity and basicity stay intuitive rather than memorized.
