Common Ion Effect on Solubility
Interactive visualization of common ion effect on solubility for 4 salts (AgCl, PbCl₂, BaSO₄, CaF₂). Log-scale solubility vs common ion concentration graph with Le Chatelier's principle explanation. Shows dramatic solubility decrease with added common ion and percentage reduction calculation.
pH Scale & Indicator Color Simulator
Interactive pH scale with 10 common acid-base indicators displayed as color-changing test tubes. Slide pH from 0-14 to see real-time color transitions for methyl violet, thymol blue, methyl orange, bromocresol green, methyl red, litmus, bromothymol blue, phenol red, phenolphthalein, and alizarin yellow R. Calculates [H⁺], [OH⁻], and pOH.
Electrolysis & Faraday's Laws
Interactive electrolysis cell simulator with Faraday's law calculations. Explore 4 electrolysis types (Cu plating, Ag plating, NaCl molten, Al smelting) with visual cell diagram showing cathode/anode reactions. Adjustable current and time with step-by-step Q→mol e⁻→mol product→mass calculation.
Entropy & Spontaneity Predictor
Interactive ΔG = ΔH − TΔS graph with adjustable enthalpy, entropy, and temperature. Visualizes Gibbs free energy vs temperature with spontaneous/non-spontaneous shading. Automatically determines crossover temperature and classifies into 4 ΔH/ΔS sign combinations with detailed explanations.
