1. Site Identity

Suggested title

Solute

Suggested subtitle

Understand matter. Predict change. Learn to think at the molecular scale.

One-sentence description

Solute is a free, self-paced college chemistry course. General Chemistry I combines clear lessons, worked problems, simulations, and laboratory practice — and its glossary and reference pages keep expanding past the module sequence into equilibrium, kinetics, electrochemistry, nuclear chemistry, and organic chemistry.

  2. Explore Chemistry Topics
  3. Open the Study Toolkit

Tone

Clear, rigorous, curious, and non-patronizing. Explain specialized vocabulary when it first appears. Connect symbolic equations to observable events and particle-level models. Avoid presenting chemistry as memorization: the recurring message is that structure, energy, electrostatic attraction, and conservation laws make chemical behavior predictable.

Hero

Chemistry explains what matter is, how it is arranged, and why it changes.

Learn to move among three views of the same event: what you can observe, what particles are doing, and how symbols and equations represent the process. This free course begins with measurement and builds toward molecular structure, energy, gases, and intermolecular forces.

What you will learn

By the end of the course, you will be able to:

  • measure and report quantities with appropriate units and uncertainty;
  • use atomic structure and the periodic table to explain chemical behavior;
  • translate among names, formulas, particles, moles, mass, and solution concentration;
  • write and interpret balanced molecular, complete ionic, and net ionic equations;
  • solve stoichiometric, thermochemical, gas-law, and solution problems;
  • construct Lewis structures and predict molecular geometry and polarity;
  • connect bonding and intermolecular attractions to measurable properties;
  • plan, document, analyze, and communicate safe chemical investigations.

How the course works

Each module contains a short orientation, learning targets, original lessons, worked examples, visual or interactive models, low-stakes practice, a mastery check, and a connection to laboratory evidence. Students should expect to spend nine to twelve hours per week at the recommended pace, including laboratory time.

Three levels of chemical thinking

Chemists constantly connect:

  1. Macroscopic evidence — color, temperature, mass, pressure, precipitates, and other observations.
  2. Particle-level models — atoms, ions, molecules, collisions, attractions, and energy distributions.
  3. Symbolic representations — formulas, equations, graphs, units, and calculations.

A strong explanation uses all three levels and states how they support one another.

  • Interactive periodic table and element profiles
  • Dimensional-analysis practice builder
  • Equation-balancing workspace
  • Molecular-shape viewer
  • Gas-law graph explorer
  • Lab safety decision scenarios
  • Searchable glossary and formula reference

Public safety statement

Reading about chemistry is not the same as being trained to perform laboratory work. Do not reproduce experiments outside an approved laboratory. Follow the supervising instructor, institution-specific standard operating procedures, chemical hygiene plan, safety data sheets, and emergency instructions.

4. About Page Copy

Mission

Solute makes the reasoning of general chemistry visible. The site emphasizes evidence, models, conservation, proportional thinking, and safe practice. It provides a coherent path through the subject while allowing learners to revisit individual topics as a reference.

What this site is

  • A complete first-semester college course
  • A searchable reference for foundational chemistry
  • A collection of original explanations and worked examples
  • A guided path into trusted, free scientific resources
  • A framework instructors can adapt to local schedules and policies

What this site is not

  • A substitute for institution-approved laboratory supervision
  • A source of medical, environmental-response, or industrial safety advice
  • A complete, graded treatment of equilibrium, kinetics, electrochemistry, nuclear chemistry, or organic chemistry — the glossary orients; it doesn't replace a full course
  • A replacement for local academic, disability, privacy, or emergency policies

5. Standard Lesson Page Template

Every topic page should use the same order:

  1. Why this matters — a concrete phenomenon or problem.
  2. Learning targets — three to six observable outcomes.
  3. Before you begin — prerequisite knowledge and estimated time.
  4. Core explanation — short sections with meaningful headings.
  5. Representations — observable, particle, symbolic, graphical.
  6. Worked examples — reasoning first, calculation second.
  7. Common wrong turns — misconception plus correction.
  8. Try it — immediate practice with expandable feedback.
  9. Interactive or data activity — simulation, graph, or database.
  10. Summary — five to eight retrieval statements.
  11. Mastery check — mixed conceptual and quantitative items.
  12. Next step — explicit connection to the following module.

6. Website Functional Requirements

  • Search by topic, formula, symbol, and glossary term.
  • Preserve mathematical notation as accessible MathML where possible; use readable text alternatives.
  • Let students reveal hints before solutions.
  • Display units in every quantitative answer and reject dimensionally invalid input.
  • Allow keyboard operation for every interaction.
  • Never encode charge, phase, hazard, or correctness using color alone.
  • Provide text equivalents for molecular diagrams, orbital diagrams, plots, and animations.
  • Add captions and transcripts to video and audio.
  • Respect reduced-motion preferences.
  • Let learners print modules, formula sheets, and lab worksheets cleanly.
  • Label external links and identify downloadable file types.
  • Record completion locally or through an LMS only with clear privacy notice.
