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 ...

ACE OF BASE A paper-based device titrates basic solutions of NaOH. The numbers at the end of each spoke indicate the concentrations of potassium hydrogen phthalate, which neutralizes NaOH, in the ...

The process of carrying out a titration allows us to accurately measure the volumes of an acid and an alkali required for neutralisation. An indicator will be used to determine the exact volume ...

METHODS for the determination of ascorbic acid have recently been much discussed. Tillmans' method, as modified by Harris and Ray 1, is generally accepted as more specific and simpler than the other ...

In a paper to the recent Faraday Society discussion on colloidal electrolytes, one of us (R. K. S.) pointed out that some of the difficulties encountered in the acid titration of proteins would be ...
