A student adds a drop of universal indicators to 1 ml of a given solution what is the ph range of the solution if dark blue color is obtained
Answers
Explanation:
the ph range is 11 which is basic (alkaline)
Answer : The pH range of the solution is 8 to 11.
Explanation :
Indicators : It is a substance that gives the visible sign by the color change of the chemical species like an acid or a base.
Universal Indicator : It changes color when mixed with an acid or base.
Universal Indicator turns red when it is added to a strong acid, it turns blue or purple when it is added to a strong base and it turns a yellowish-green when it is added to a neutral solution.
The pH range is, 1 to 14.
When the value of pH is less than 7 then the solution is acidic.
When the value of pH is more than 7 then the solution is basic.
When the value of pH is equal to 7 then the solution is neutral.
From the given problem, we conclude that the when a student adds a drop of universal indicators to 1 ml of a given solution and the color of the solution obtained is dark blue. So, the value of pH will be greater than 7 and the pH range will be, 8 to 11.
Hence, the pH range of the solution is 8 to 11.
