JordanAn observable reaction is a change that can be measured, detected, or witnessed during a chemical or physical process. This can include changes in color, temperature, precipitation, gas formation, or the release of light or sound. It provides evidence that a chemical reaction or a physical change has occurred.

List four requirements of an ideal titration?
A clear endpoint where a color change or other observable change indicates the completion of the reaction. Accurate measurements of the volumes of reactants used. A well-calibrated burette for precise delivery of titrant. Use of an appropriate indicator to signal the endpoint of the titration.
What can be evidence of a chemical reaction?
Evidence of a chemical reaction can include formation of a gas, color change, temperature change, formation of a precipitate, or production of light. These observable changes indicate a transformation of substances into new molecules with different properties.
How can one tell if a reaction has reached equilibrium?
All motion ceases
How do you describe titration?
Titration is a laboratory technique used to determine the concentration of a substance in a solution by slowly adding a reagent of known concentration until a reaction is completed. This reaction is typically indicated by a color change or other observable change. Titration is commonly used in chemistry for analyzing acids, bases, and other substances.
What is the observable change for burning a log?
The observable change for burning a log is the production of heat, light, and smoke.
