The indicator that have different ph range is
WebThe pH indicator solution is orange when the pH range is between 4.5 and 6. Bromothymol Blue varies from yellow to blue, which means at low pH (6 and lower), the indicator displays yellow colour, and at high pH (7.5 and above), it turns blue. The indicator turns greenish when the pH value is between 6 and 7.5. Universal Indicator pH Scale WebThe pH scale and universal indicator colours. 1; 2; 3; Page 1 of 3; Glossary.

WebAnswer (1 of 2): Indicators are weak acids or bases and as such they change their form as the pH changes. When the pH is numerically equal to the pKa of the indicator, it will be 50% acid form, 50% base form. When the pH is 1 unit higher it is 10% acid form, 90% base form, 2 units higher (pH = pK...
