Define the end point of a titration. It is when a change that indicates equivalence is observed in the analyte solution. It is a synonym for equivalence point. It is the point at which the pH no longer changes.

Answer : The correct option is, It is when a change that indicates equivalence is observed in the analyte solution.

Explanation :

Titration : It is a laboratory process where we have to use the volume of a solution of known concentration to determine the concentration of unknown solution.

Titrations mostly occur in redox reactions and acid-base reactions.

During the process of titration, there are two important stages which are endpoint and equivalence point.

Equivalence point : It is a point in which the added titrant is equivalent to the analyte in the sample.

Endpoint : It is a point where the indicator changes its colour that means it is a change that indicates equivalence observed in the analyte solution.

Hence, the correct option is, It is when a change that indicates equivalence is observed in the analyte solution.

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
