Chemical Poisoning
Chemistry
Definition Chemical poisoning is a major public health concern. Approximately 95% of all accidental or intentional poisonings are due to chemicals. Nearly 90% of these cases occur at home. The smallest children, infants and toddlers, are at the highest risk for accidental (acute) poisoning. In 2000, poison control centers received well over a million calls…
Electrochemical Cells Lab
Chemistry
Determination of an Electrochemical Series In electrochemistry, a voltaic cell is a specially prepared system in which an oxidation-reduction reaction occurs spontaneously. This spontaneous reaction produces an easily measured electrical potential which has a positive value. Voltaic cells have a variety of uses and you commonly refer to them as a “battery”. Half-cells are normally…
