Abstract
Brusnicom, Vaccinium sp. L, se naziva nekoliko vrsta grmolikih biljaka koje pripadaju porodici vrijesova, Ericaceae. Ove biljke su raširene po sjevernoj hemisferi, a poznate su po svojim sjajnim crvenim plodovima. Plodovi su bogati raznim vitaminima i mineralima te su zastupljeni u raznim prehrambenim proizvodima. Boja ploda govori da se u plodu nalaze spojevi koji bi pri pojedinoj pH vrijednosti mogli dati drugačiju boju, stoga bi plodovi brusnice mogli poslužiti u pripremi prirodnih kiselo-baznih indikatora. U radu su pomoću svježih plodova brusnice i odabranih otapala (metanol, etanol, aceton, hladna i vruća voda) pripremljene otopine indikatora. Cilj ovog rada je bio utvrditi bolje otapalo za pripremu indikatora te ispitati njihovu trajnost. Indikatori su se pokazali dugotrajnima, a osim toga imaju i niz drugih prednosti (niska cijena, jednostavna nabava, jednostavna i brza priprema, manja opasnost, manje ili nimalo otpada). Na temelju ovih rezultata, može se uvidjeti da se ovakvi indikatori mogu upotrebljavati u školstvu – u nastavi kemije.
Abstract (english)
Cranberry, Vaccinium sp. L, refers to several species of shrub plants belonging to the heath family, Ericaceae. These plants are spread throughout the northern hemisphere and are known for their shiny red fruits. The fruits are rich in various vitamins and minerals, and are present in various food products. The colour of the fruit indicates that there are compounds in the fruit that could give a different colour at a certain pH value, so cranberry fruit could be used in the preparation of natural acid-base indicators. In this thesis, indicator solutions were prepared using fresh cranberry fruit and selected solvents (methanol, ethanol, acetone, cold and hot water). The aim was to determine a better solvent for the preparation of indicators and to test their durability. Indicators have proven to be long lasting; and also have a number of other advantages (low cost, simple supply, simple and easy preparation, safe, little or no waste). Based on these results, it is observed that such indicators can be used in education – in chemistry classes.
