This is an unofficial free web quiz for practicing acids and bases in high school Chemistry Basic.
All questions, choices, hints, diagrams, and numerical settings are independently created for this app. They are not copied from textbooks, workbooks, entrance examinations, mock tests, school handouts, or official learning materials.
The quiz focuses on common chemistry facts and laws such as pH, H+ and OH−, molarity, neutralization mole ratios, and acid-base titration.
Hints change depending on the current problem. They include original simplified SVG diagrams for pH scale, molarity, neutralization, titration setup, indicators, and acid/base classification.
This quiz is also useful for searches such as pH calculation practice, hydrogen ion concentration questions, hydroxide ion concentration review, neutralization calculation, acid-base titration, molarity, indicators, equivalence point, titration curve, and salt solution properties.
Each course is designed for short practice sessions, so learners can focus on one weak point such as converting mL to L, using n = C × V, checking acid/base valence, or choosing an indicator near the endpoint.
The app is designed as an unofficial study aid. It uses general chemistry facts, formulas, units, and common substance names, while the questions, numerical values, answer choices, hints, and diagrams are newly created for this site.
