Precipitation Titration: Endpoint Detection Methods
0 Views •
2025
In argentometric precipitation titrations, endpoints can be detected visually by the Mohr, Volhard, and Fajans methods. In the Mohr method, adding a soluble chromate indicator gives an initial yellow color to the analyte solution. As the titrant is added, the first excess of silver ions forms a red silver chromate precipitate, marking the endpoint. The solution pH should be maintained at about 8 by adding solid CaCO3. In the Volhard method, a standard excess of AgNO3 is first added to the...

Here, we present a protocol to establish important endpoints and proliferative markers of small intestinal injury and compensatory hyperproliferation using a model of chemotherapy-induced mucositis. We demonstrate the detection of proliferating cells using a cell cycle specific marker and using small intestinal weight, crypt depth, and villus height as endpoints.

Evaluating the Accuracy of Snap Judgments

Source: Diego Reinero & Jay Van Bavel—New York University Social psychologists have long been interested in the way people form impressions of others. Much of this work has focused on the errors people make in judging others, such as the exaggerated influence of central traits (such as "warm" and "cold"), the insufficient weight given to the context in which others' behavior takes place, and the tendency for people to make judgments that conform to their initial expectations about another.

Self-Evaluation: Self-Enhancement and Self-Verification

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

High Content Screening Analysis to Evaluate the Toxicological Effects of Harmful and Potentially Harmful Constituents (HPHC)

The objective of the study was to assess the biological impact of 15 cigarette smoke constituents using a combination of an impedance-based real time cell analyzer and a high-content screening (HCS)-based platform for toxicological assessment in vitro. This study provides information on effective doses, toxicity and modes of action of the tested compounds.
FAQs
An attained endpoint can be tested by substituting its coordinate into the function, so its resulting value belongs to the function’s output. An open endpoint does not contribute an attained value at that boundary. Its nearby behavior must instead be described with a one-sided limit, which distinguishes a boundary trend from a value actually included in the function.
A one-sided limit describes how a function behaves as its input approaches an endpoint from within the specified interval. This is necessary when direct substitution is impossible because the function is undefined at the boundary. Comparing the limiting behavior with the endpoint’s domain status helps determine whether the boundary represents an actual function value or only an unattained trend.
Domain restrictions determine whether an endpoint is available for substitution and whether its function value can be included in a conclusion. They also identify boundaries where continuity must be tested through appropriate limiting behavior. Consequently, the same algebraic expression can lead to different endpoint interpretations depending on whether the boundary belongs to the function’s domain.
First, identify the interval boundaries and determine whether each endpoint is included in the domain. Substitute an included endpoint into the function and simplify the result. If direct evaluation is undefined or the boundary is open, examine the appropriate one-sided limit instead. Record separately whether the boundary has an attained value or only limiting behavior.
On a closed interval, evaluating the function at the endpoints supplies boundary values that must be considered when identifying absolute maxima and minima. These results can then be compared with the function’s behavior elsewhere on the interval. Omitting an included endpoint could therefore lead to an incomplete or incorrect conclusion about the function’s largest or smallest value.
Endpoint analysis clarifies whether a graph reaches a boundary or merely approaches it, using attained values, open boundaries, and one-sided limits. In optimization, this information shows whether a boundary candidate is actually available. In graph analysis, it also helps connect domain restrictions, continuity, and boundary behavior into a more accurate interpretation of the function.
