Introduction ((((Fluoride in teatime sample)) - Essay ExampleThe Nernst equivalence is valid for very dilute solutions or solutions with constant ionic strength. Fluoride ion selective electrode responds to free ionized fluoride in solutions. This experiment aims to demonstrate the use of fluoride ion selective electrode (FISE) in the determination of fluoride concentration (TSU, 2013).Tea (Carmelia sinensins) is naturally rich in fluoride. Plants absorb nutrients (inclusive of fluoride) from the soil). Most of these nutrients are stored in the leaves which for the case of teatime are harvested for tea prep due to easy harvesting, handling and brewing. New tea preparation techniques and consumption are deemed to have implications on the fluoride concentration. Josipa et al., (2012) determined fluoride concentration in various infusions of tea using fluoride ion selective electrodes which is a simple and fast method. In the study it was discovered that the size of tea pieces great ly influences levels of fluoride in tea infusion. The finer the tea material, the grater the extraction of fluoride. Brewing time was found to also affect the concentration of fluoride in tea infusions. Brewing times of between 10 to 20 legal proceeding gave optimal concentrations of fluoride especially for mint and pomegranate tea. It was advised that one should drink tea prepared more than 24 hours prior to preparation. Strong correlation were observed between concentration with change of time and also packaging effect especially for green tea.Josipa Giljanovi, Ante Prki, Marija Brali, Mia Brkljaa (2012).
