What is the colour of methyl orange at endpoint?
yellow
Unlike a universal indicator, methyl orange does not have a full spectrum of color change, but it has a sharp end point. In a solution becoming less acidic, methyl orange changes from red to orange and, finally, to yellow—with the reverse process occurring in a solution of increasing acidity.
What color is the endpoint for phenolphthalein?
pink
When phenolphthalein is the indicator, the end point will be signified by a faint pink color.

What is the colour of end point?
The end point (or end-point) of an acid-base titration is when the indicator changes colour during a titration. The colour at the end point is referred to as the middle tint.
What is methyl orange endpoint?
When Methyl Orange Indicator Solution is used, the endpoint color change is from red to orange. Color or turbidity in the sample can make it difficult to see the color change at the endpoint. The end point for methyl orange acidity is pH 3.7.
What is end point in chemistry?
end point: the point during a titration when an indicator shows that the amount of reactant necessary for a complete reaction has been added to a solution.

End Point. end point: the point during a titration when an indicator shows that the amount of reactant necessary for a complete reaction has been added to a solution.
What is phenolphthalein alkalinity and methyl orange?
A measure of the total amount of hydroxyl ions in a solution as determined by titration with standardized acid and methyl orange indicator. There are two pH endpoints, P and M, in this titration, corresponding to phenolphthalein and methyl orange indicators.
