Two types of acid-base titration stand out: alkalimetry and acidimetry. Each method provides a precise means to measure ...

An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...

A crash course on the basic differences between acids and bases. A crash course on the basic differences between acids and bases, complete with a classroom-friendly experiment demonstrating the ...

The pH of acidic, basic, and neutral aqueous solutions of salts is shown with ammonium chloride, sodium acetate, and sodium chloride. Place beakers containing distilled water and universal indicator ...

The pH scale measures the acidity or alkalinity of a substance, ranging from 0 to 14, with values below 7 representing acidity, above 7 representing alkalinity, and 7 representing neutrality.

Students will be able to explain that if two substances cause turn a pH indicator different colors, they must be different substances. Students will be able to explain that the color that a substance ...

The pH is a negative logarithmic scale, which measures the molar concentration of hydrogen ions from 1 to 10 14 ions. It therefore has no unit of measurement. Numbers on a negative logarithmic scale ...
