The acid dissociation constant, K a, and its negative decadic log, pK a, are key life sciences parameters that describe molecular acidity. Specifically, these values indicate the protonation state of ...
A well-established technique, acid-base titration is an analytical method used to determine the concentration of an unknown acid or base. In practice, it involves adding a solution of known strength ...
Microfluidic paper-based analytical devices (µPADs) have gained significant attention in analytical science and technology due to their numerous advantages over traditional analytical techniques, ...
QUANTITATIVE methods of paper chromatography tend to be unsatisfactory largely because of the very small amounts of substance separated. In the case of sugars, the spots are generally located by guide ...
IN work directed toward the separation of several volatile 2-halogenated carboxylic acids by paper chromatography, it was found desirable to develop these acids, not, as is usually the case, in the ...
Change the atmosphere to change the water below. Create a carbon dioxide–rich atmosphere in a cup and watch how it changes the water beneath it. This model of ocean-atmosphere interaction shows how ...
Note: This video is designed to help the teacher better understand the lesson and is NOT intended to be shown to students. It includes observations and conclusions that students are meant to make on ...
Our nearest planetary neighbor may be more friendly to life than we previously thought. Venus has long been assumed to be uninhabitable: its thick carbon dioxide atmosphere is swirling with yellow ...
pH is a measurable parameter between the values of 0 and 14, defining the acidity or alkalinity of a solution. Solutions with a pH = 7 are considered neutral, pH < 7 are considered acidic and pH > 7 ...
