What is the colour of Mn2 plus ion in estimation of iron 2 by permanganometry?
The color of Mn2+ ion in estimation of iron 2 permanganometry is purple.
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.
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 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.
What is the difference between the endpoint method and the kinetic reaction method?
The endpoint method is used in titration to find the exact point at which the reaction is complete, often indicated by a color change. The kinetic reaction method involves monitoring the rate of reaction to determine the endpoint based on changes in the reaction rate. Both methods are used to quantify the concentration of a substance in a sample.
Why you use phosphoric acid during permanganometry titration?
Phosphoric acid is used in permanganometry titration to stabilize the manganese dioxide formed during the reaction of potassium permanganate with hydrogen peroxide. This helps to prevent premature oxidation of the permanganate ion, ensuring accurate endpoint determination. Additionally, phosphoric acid acts as a buffering agent, maintaining a relatively constant pH during the titration process.
