pKa value using a pH meter

Similar to the Potentiometric estimation, a different electrochemical estimation method is, using the pH Meter to calculate the concentration of H+ Ion, and thus pH of solution or pKa of acid and similar quantities, so Let’s discuss one Experiment, 623 more words

Potentiometric Estimation

Electrochemical analysis is the group of chemical analytical methods in which a potential change is generated by the electrochemical reaction involved.

What is the real picture, in simple words the chemical change here is measured by the change in potential. 699 more words

Lecture 1.104- Reference Electrode

Imagine a glass of water, and an ice cube. What can we say about the temperature of the water, it’s hotter (with respect to the ice cube) but similarly, But when we have some hot soup near it the same glass is colder (with respect to soup thins time). 579 more words

1.102- Why a Salt Bridge?

Why do we need a Salt Bridge?

Reviewing, the last thing we studied Mechanism of Electrochemical cell, we made it work without a salt bridge, and in fact it will, But not for long, the reason is better explained if we analyse what is happening next in the solution. 373 more words

“Ah, Paul Rozin is sort of orthogonal to this whole debate.”

I can’t remember who said it, but I do remember the tone: awestruck, almost reverential, but with a touch of uncertainty as well. 1,079 more words

Colorimetry - coloring chemistry

In physical and analytical chemistry, colorimetry or colourimetry is a technique “used to determine the concentration of colored compounds in solution.”We know when any intensity (say Io) of light fall on the surface of a substance, three processes occur : Absorption, Reflection, Transmission. 755 more words
