during the lab, you will have access to a range of acids and bases as well as universal ph indicator paper. think about how you can use these tools to develop a color chart for the red cabbage indicator. then, write a hypothesis using the \if/then\ format.\nhypothesis:\n\ndone
Answer
Brief Explanations:
A hypothesis in an acid - base experiment using red cabbage indicator can be formed based on the known property of indicators changing color with pH. Red cabbage contains a pigment that acts as an indicator. We know that acids and bases have different pH values and universal pH indicator paper can show pH levels. So, we can assume a relationship between the pH (tested with universal pH paper) and the color of the red cabbage indicator.
Answer:
If the pH of a solution, as determined by universal pH indicator paper, is low (acidic), then the red cabbage indicator will turn a certain color (such as red - pink); if the pH is high (basic), then the red cabbage indicator will turn a different color (such as blue - green).
