Identify the independent (manipulated) and dependent (responding) variables in a scientific investigation. Draw conclusions about the relationship between two variables using quantitative data.

Many potential drug candidates fail to advance because of a lack of clinical activity at tolerated doses or because of unmanageable toxicities. Other limitations include a deficit of drug-like ...

Most organic drugs contain one acid group, usually a carboxylic acid, -COOH, or one basic primary, secondary, or tertiary amino group, NC 1-3, [3,22,27,28,29] that determines the acid-base reactivity ...

Sodium butyrate—more properly sodium butanoate—is a salt of butyric (butanoic) acid. If it comes into contact with even a trace of moisture, it emits a faint odor of its foul-smelling conjugate acid.

An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...

This lab includes a demonstration of the proper use of a burette system for titrations; including a detailed description, instructional video, and opportunity for students to collect data to ...

How did you discover MCBAs? Bile acids were first described chemically in 1849, and Heinrich Wieland was awarded a Nobel Prize in 1927 for comprehensively describing their chemistry. This description ...
