Q.4--- Methyl orange is a weak acid, it changes it's colour according to the pH.
In acidic medium it gives red colour
In basic medium, it gives yellow colour.
Sodium bicarbonate is a base so methyl orange will give yellow colour in it.
Q.6---CO2 is highly soluble in water which forms carbonic acid in water which is acidic in nature therefore it turns pink by adding drops of phenolphthalein .
HOPE THIS HELPS....
