Hello diven, let's look at the question.
00:03
Now in this question it is given that, so there is a, uh, uh, what acid -based indicator solution which turns to different colors depending on the weak acid or its conjugate predominance.
00:15
So here there is a weak acid, h a, a, and so this dissociates as h plus and a minus, aquius, aquas and aquas, okay.
00:30
Now, so here we have taken an acid.
00:33
Base indicator and here in the acidic form it is giving color one and in its conjugate basic form it gives a color two so it depends on which of the side predominates in an equilibrium right now here what we have done is we have added an a which here now after adding any which so what color will be the what the solution right that means which color predominates now it depends on which side of the plurum predominates right so when you add an a which what happens that it will react with the h plus giving water so here so n a which since it is a base it will react with the h plus present in the reaction mixture and it gives water and n a plus now you can see that the concentration of h plus decreases when you add an a hoh right when the concentration of the h plus decreases equilibrium will shift towards the right side okay so so when that happens, the a minus concentration increases, right? that means the color 2 will be what predominant...
