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 ...

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 strength of an acid or base affects the pH more significantly than the concentration of the acid or base. The strength of an acid or base is how likely it is to donate or accept a proton in an ...

Repeat step 1 with ethanoic acid into a separate test-tube. Add 5 drops of Universal Indicator to each test-tube and record the pH, or use a pH meter to record the pH. You should find that ...

(aq)\) This is a reversible reaction. A small proportion of ... Adding water to an acid or base will change its pH. Water is mostly water molecules so adding water to an acid or base reduces ...
