A solution turns phenolphthalein indicator pink. The most likely pH of this solution will be
Answers
Answer:
Every substance with a pH greater than 7 is considered basic or alkaline. Basic or alkaline solutions turn phenolphthalein indicator pink. Thus, the pH of the solution is most likely 9.
Conclusion
pH
In chemistry, the pH scale is used to define the acidity or basicity of an aqueous solution. pH has historically stood for "potential of hydrogen" (or "power of hydrogen"). Lower pH values are recorded for acidic solutions (solutions with higher H+ ion concentrations) than for basic or alkaline solutions.
The set of standard solutions whose pH has been defined by international agreement can be used to trace the pH scale. Using a concentration cell with transference, the potential difference between a hydrogen electrode and a standard electrode, such as the silver chloride electrode, is measured to get the primary pH standard values. With the use of a glass electrode, a pH meter, or a color-changing indicator, the pH of aqueous solutions can be determined.
Main Content
A substance is defined as basic or alkaline if its pH value is more than 7. The phenolphthalein indicator turns pink in basic or alkaline liquids. Consequently, the solution's pH is probably 9.
