In 1st tube , it is acid because it turns red in color
In 2 nd tube, it is base because it turns yellow in color

Why red color is coming while adding acid in sollution

[@lalitkumar2659]

Because the acid donates protons to the water molecules . Thus, these increase the concentration of H3O+ ions in the solution. These H30+ donate proton to the indicator molecule hence they causing change color toward red.
