2. Methyl red appears read a at PH<6.6 but change to red at PT "ppears read at PH<4.8 but change to yellow at PH>6.0; phenol red appears yellow change to red at PH>8.0 If a solution is yellow when methyl red and phenol Test are added separately, the solution PH is in the range
e aqueous solution of salt NaC2H3O2 is

Answers

#2. The solution can appear yellow when methyl red is added only when pH is above 6 .

And the same solution can appear yellow when phenol red is added only when pH is less than 6.6

So by considering both conditions and as the solution appears yellow in both indicators added separately , we can say that pH range of solution is between 6 to 6.6 pH.
