Sažetak
Modern chemistry classroom includes as much experiments in learning process as possible, which can be financially demanding. Realisation of lessons often needs expensive and unavailable chemicals, what is the case with acid-base indicators as well. Our previous study has shown that various plant material can be used as an alternative acid-base indicator. In this work, previous study has been extended to include forest plants and plant materials, in order to determine whether they can be used as indicators as well. Studied plant material were various forest plants, such as wild blackberry, wild strawberry, hawthorn, wild rose, etc., as fresh material and as a plant based product (dried material, juice, tea, fruit preserves, wine, etc.). The used plant products did not have added artificial colouring or aroma, or other plant material that could affect results. In some cases, more products from different suppliers were analysed, as well as homemade products. Plant products were analysed in several concentrations and the ones with the highest concentration of fruit were chosen. Preliminary results indicate a great potential of forest plants and plant based products as acid- base indicators.
