    KMnO4,goes into excess right after all the iron has been fully oxidised.So there is a pink solution due to it going into excess.

    Yes,it changes color as acid/alkali goes into excess.We cant stop at the exact moment when its neutralized,there is still a small amount that is present and even that small amount would be in excess.

    End point is the exact point when the indicator changes color,so in this case at the end point,it would be in excess and show its color

    Y U NO SPELL MY NAME RIGHT Well we have to fine x and y and they are with C and H,so we will remove the other masses: 132-90=42 By deduction the only logical number would be 3C=12x3=36 and 6H=6.

    I believe that would be a mistake in the ms.As er states most students got the Q right and obviously H+ ions turn u.i red.
