Virtual Labs
Interactive science experiments and simulations built to explore concepts through experimentation. Manipulate independent variables, observe real-time reactions, and inspect quantitative data plots.
pH Scale & Ion Equilibrium
Explore hydronium ion concentration, hydroxide balance, and indicator spectrums.
Determine aqueous solution pH from hydronium ion molarity and observe indicator color transitions.
pH = -log₁₀[H₃O⁺] and pH + pOH = 14.00 (at 25°C)Acid–Base Titration Simulator
Simulate volumetric titrations, track pH response curves, and detect equivalence points.
Analyze neutralization curves and stoichiometric equivalence points during strong and weak acid titrations.
Mₐ × Vₐ = M_b × V_b (at 1:1 equivalence)Beer-Lambert Law Spectrophotometry
Model radiant light absorption, cuvette path length, and molar absorptivity.
Quantify the linear relationship between solute concentration, optical path length, and radiant light absorbance.
A = ε × c × l = -log₁₀(I / I₀)Chemical Reaction Kinetics
Explore reaction velocity, Arrhenius temperature dependence, and activation energy.
Analyze the influence of temperature, reactant concentration, and catalyst presence on rate of reaction.
r = k(T)[A]ⁿ where k = A₀ × e^(-Eₐ/RT)Ohm's Law & Circuit Analysis
Interact with electric potential, ohmic resistance, and electron current flow.
Verify the proportional relationship between potential difference and electric current across linear conductors.
V = I × R ⟹ I = V/R and P = V × IRefraction & Snell's Law
Simulate boundary ray optics, refractive indices, and total internal reflection.
Quantify optical ray deflection across dielectric interfaces and determine critical angles for total internal reflection.
n₁ sin θ₁ = n₂ sin θ₂ and θ_c = arcsin(n₂/n₁) (for n₁ > n₂)Measurement & Significant Figures
Master experimental measurement precision, decimal uncertainty, and rounding rules.
Apply standard scientific significant figure conventions to laboratory readings, arithmetic, and data reporting.
Measured Value = x_best ± δx (precision limited by least accurate term)More from Alok Das
These interactive tools are personal side-projects built for exploration and utility. My primary professional commitment is in M.Sc. Chemistry, analytical research, and laboratory methodology.
