Buffer System Dynamics
Visualize a macroscopic particle-level buffer system reacting to the influx of strong acids (H⁺) or strong bases (OH⁻). Observe Henderson-Hasselbalch equations dynamically adapt as the buffer capacity successfully resists dramatic pH changes.
Weak Acid/Base Titration Explorer
Perform a simulated titration dropping strong base into a weak acid. The simulator mathematically calculates real-time buffer regions, half-equivalence points, and post-equivalence spikes dynamically, plotting the exact sigmoidal pH titration curve.
Beer-Lambert Law Spectrophotometry
Visualize the principles of spectrophotometry. Adjust wavelength, concentration, and cuvette path length to observe how light absorption changes dynamically according to the Beer-Lambert Law.
Bomb Calorimetry Simulator
Simulate a constant-volume bomb calorimeter to compute the molar heat of combustion (ΔH_comb). Ignite different organic samples and dynamically measure the highly precise temperature rise to calculate the heat absorbed by the system.
Mole Concept & Stoichiometry Calculator
Convert between grams, moles, and particles. Determine limiting/excess reagents with 4 preset reactions. Calculate theoretical yield and percent yield.
Isotope Notation & Average Atomic Mass
Explore isotope notation for 7 elements. See mass number, atomic number, proton/neutron counts, and calculate weighted average atomic mass from natural abundances.
Phase Diagram Explorer
Interactive phase diagrams for H₂O and CO₂. Explore triple points, critical points, and supercritical fluid regions. Identify the phase at any T,P coordinate.
Arrhenius Equation (Rate vs Temperature)
Visualize the Arrhenius equation k = Ae^(−Ea/RT) with adjustable Ea and temperature. Compare catalyzed vs uncatalyzed reactions on a ln(k) vs 1/T plot.
2D Center of Mass Collision Simulator
Simulate 2D elastic collisions from both the Laboratory and Center of Mass reference frames. Visualize how the total momentum in the COM frame always remains exactly zero, creating perfectly symmetric scattering trajectories.
Ballistic Pendulum Conservation
Analyze the classic dual-phase conservation problem. Shoot a bullet into a block to visualize the entirely inelastic momentum transfer and instantaneous loss of kinetic energy, followed by the pendulum swing where mechanical energy is perfectly conserved.
Meselson-Stahl DNA Replication
Replicate the most beautiful experiment in biology. Centrifuge radioactive nitrogen isotopes (15N vs 14N) across bacterial generations to generate heavy, hybrid, and light DNA bands proving semi-conservative replication.
Eutrophication & Hypoxia System
Trigger an ecological collapse. Release nitrogen and phosphorus Agricultural Runoff to force an Algal Bloom, then watch the horrific spike in Biological Oxygen Demand (BOD) that strips Dissolved Oxygen (DO) and causes an aquatic Dead Zone.
