The common indicator cannot give us the strength of acid and base. To measure the strength of acid and bases we need a universal indicator. Universal indicator is a mixture of different indicators which give different colour at different pH value of entire scale.
(a) Universal indicator is a mixture of many different indicators which gives different colours at different pH values of the entire pH scale. It is used to obtain an idea of how acidic or basic a substance is.
Weak - Yellow. As, pH = 1, it is very strong. So, Hydrochloric acid turn universal indicator into red colour.
Therefore, the resultant neutral solution will give green colour with a universal indicator. $$\text{Note:}$$ Resultant indicator show green colour when the pH of the solution is 7. Was this answer helpful?
Universal indicator shows yellow colour when added to a solution at 25 0 C. If its concentration is changed such that the same indicator shows red colour, then identify the correct statement. If its concentration is changed such that the same indicator shows red colour, then identify the correct statement.
A Universal indicator is a pH indicator composed of a solution of several compounds that exhibits several smooth colour changes over a pH value range from 1-14 to indicate the acidity or alkalinity of solutions. It turns red on treating with a strong acid whereas it turns purple with a strong base.
Universal indicator is a brown coloured solution containing a mixture of indicators, that can be added to any substance to determine its p H. It changes colour in different p H environments. At p H range of 8 − 11 , the colour is blue.
Universal indicator shows yellow colour when added to a solution at 25 0 C. If its concentration is changed such that the same indicator shows red colour, then identify the correct statement. If its concentration is changed such that the same indicator shows red colour, then identify the correct statement.
A universal indicator is a blend of p H indicator solutions made to identify the p H of the solutions over a wide range of values. Universal indicator is a mixture of many indicators such as- Thymol blue, methyl red, bromothymol blue and phenolphthalein.
Blue. A Universal indicator is a pH indicator composed of a solution of several compounds that exhibits several smooth colour changes over a pH value range from 1-14 to indicate the acidity or alkalinity of solutions. It turns green in presence of a neutral compound. Raw cow's milk has neither acidic nor basic effect on body hence it is neutral.
