Findings From Investigation

3 days later, changes did occurred on all plants. Firstly, the plant growing in the acidic environment wilted and its roots turned into red colour. Secondly, plants growing in liqiuids with neutral pH values thrived. However, the one growing in a slightly acidic environment/distilled water had grown better than the one growing in the control setup. Lastly, those growing in liquids with higher pH values wilted and all their leaves had shrunk. However, growth of the water hyacinth growing in the mixture of toothpaste and tap water (pH 10.2) is better than the one growing in the extremely alkalic liquid (Dilute sodium hydroxide, pH 14.0), because no changes observed from its roots while the other hyacinth’s roots turned into red colour too.
