|
Indicators Indicators are dyes which are sensitive to protons from acids and which change color in their presence or absence; indicators usually undergo reversible color changes |
Amphoteric Behavior of Aluminum Carbon Dioxide from Respiration

|
Peroxides Peroxides are chemicals characterized by the presence of an oxygen-oxygen bond, such as found in hydrogen peroxide and benzoyl peroxide |
|
|
pH pH is a measure of the concentration of protons in a solution; protons are hydrogen cations |

Precipitates Precipitates are solids usually of crystalline composition which are only partially soluble in solvents; a precipitate will normally "fall" to the bottom of a reaction vessel as it forms, hence the word |
