What is the colour of Mn2 plus ion in estimation of iron 2 by permanganometry?
In the estimation of iron(II) by permanganometry, the Mn2+ ion acts as an indicator. The Mn2+ ion itself is colorless in solution. During the titration process, the Mn2+ ion is oxidized to Mn4+ by the iron(II) ion, resulting in a color change from pale pink to colorless. This color change is used to determine the endpoint of the titration.
Two rays that share an endpoint determine an angle?
Yes.
Two rays that share an endpoint determine an angle True or false?
true - apex
How do you find the endpoint of an endpoint?
The endpoint has no dimension. It has no endpoint.
What changes color at the endpoint of titration?
The color change at the endpoint of titration is usually due to an indicator that has been added to the solution being titrated. The change in color indicates that the reaction is complete and can help determine the endpoint of the titration.
Is phenolphthalein an indicator?
Yes, phenolphthalein is an indicator commonly used in acid-base titrations to determine the endpoint of the reaction.
What is endpoint in titration?
In titration, an endpoint is the point at which the reaction between the analyte and titrant is complete. It is often indicated by a significant change in color or another physical property of the solution, signaling that the equivalence point has been reached. The endpoint helps determine the concentration of the analyte in the sample being analyzed.
The midpoint of JK is point L at ( and ndash1 8). One endpoint is J(4 and ndash15). Which equations can be solved to determine the coordinates of the other endpoint K Check all that apply?
If endpoint J is at (4, 15) and midpoint L is at (1, 8) then endpoint K is at (-2, 1) Because (4-2)/2 = x and (15+1)/2 = y for midpoint (1, 8)
Does a line have an endpoint?
No, lines are ongoing, and have no endpoint.
What is the other endpoint of the line segment with the given endpoint and midpoint. Endpoint (6-9) midpoint (76)?
If you mean endpoint (6, 9) and midpoint (7, 6) then the other endpoint is (8, 3)
What is meant by internal indicator?
Sometimes one of the reactants in a titration act as an indicator; this is an internal indicator. An example is the volumetric technique of permanganometry.
What is the difference between rough and accurate titration?
Rough titration is an initial estimation to determine the approximate endpoint of a titration, while accurate titration involves fine adjustments to precisely determine the endpoint. Rough titration is typically done quickly and gives a ballpark figure, whereas accurate titration is more meticulous and provides a precise measurement.
