Question

The colour of methyl orange indicator turns yellow in a solution. The pH of this solution            is likely to be                                                                                                        
 a) 7                                         b) less than 7        c) 0                                         d) more than 7

Answer 2

Answer:

b) less than 7

Explanation:

Because they have such vivid color changes, only small amounts of indicators must be added to a solution which also limits any side effects they might have on the reaction being observed. At pH values less than 3.1, methyl orange is red and a pH values greater than 4.4, it will be yellow
