hope this answer helps!!!
Answer:
We cannot use hydrogen peroxides and chlorine bleach as a natural indicators because they are dissociated into its ions and changes their pH of dissociation.
Explanation:
Natural indicators are organic material that they formed by natural tissues and these are cannot be broken down into the further ions. Hence the pH value is cannot be vary.
If we use hydrogen peroxide and chlorine beach as as natural indicators these are further broken down into its ions and change their pH of dissociation.
Hence, we cannot used as a natural indicators.
