This lab includes the complete titration procedure used to investigate how well a buffer resists changes in pH. Prepare a buffer solution by accurately calculating and measuring the required amounts ...

Each chemical reaction involves an enthalpy change that leads to a change in temperature. The amount of substance converted during the reaction determines the increase (i.e. exothermic reaction) or ...

It is thought that without the use of fertilizers, around half of the world’s population could not be supported 1. In the modern world, agriculture at a significant scale without fertilizers is no ...

Titration is an analytical chemistry technique used to find the concentration of an unknown solution, using a solution whose concentration is known. The latter is called the titrant and is usually ...

One of the most commonly used varieties of plastic are polyurethanes. They are created from the reaction of raw polyols with isocyanates. A large variety of plastics can be acquired depending on the ...

IN a previous paper 1 it was claimed that the addition of small amounts of copper sulphate to a suspension of acid-washed organic matter resulted in the release of two hydrogen ions for each of added ...
