in an experiment where red cabbage water is prepared and cooled to be used as an indicator for acids and bases, what will be the observation, dependent and independent variable?
Observation: The color change of the red cabbage water when an acid or base is added to it.
Dependent variable: The color change of the red cabbage water.
Independent variable: The acid or base that is added to the red cabbage water.
In the experiment where red cabbage water is prepared and cooled to be used as an indicator for acids and bases, the following are the observations, dependent variables, and independent variables:
Observation: The color change in the red cabbage water after it is exposed to different substances (acids and bases).
Dependent Variable: The color change in the red cabbage water is the dependent variable. It is the variable that is being measured or observed as a response to the different substances.
Independent Variable: The independent variable in this experiment is the different substances (acids and bases) to which the red cabbage water is exposed. The researcher will deliberately manipulate and control the types of substances used.
