Question

In the process of titration, what color is the solution before methyl orange is added to it?

Answer 1

Answer:

Methyl orange has the property to color alkaline and neutral water yellow. If the water becomes acidic, it turns red immediately. The point of change is at pH 4.3. If the solution is yellow, hydrochloric acid at a concentration of 0.1 mol/L is used for the titration.
