Abstract
This experiment focused on the effects of sulfuric acid to the agricultural plant, sunflower (Hellianthus annuus) and the research question is “How is the growth of Helianthus annuus (Sunflower) in terms of height (cm) effected by different concentrations of sulfuric acid (H2SO4) solutions added to different groups while the soil quality, temperature and pressure is tried to be constant for all groups?” This research is focused on the effects of different concentrations of acidic solution on Helianthus annuus (Sunflower) plant. Acidic solutions was obtained from mixing sulfuric acid (H2SO4) with water. 0, 25, 50, 75 and 100 mililiters of acid is present in 1 liter (1000 mL) solutions respectively. The samples were observed for 20 days and their growths were measured. There was a clear difference in growth between the groups. Experimental results supported my hypothesis that is ‘’Different concentrations of sulfur dioxide solutions will affect the growth rate of Hellianthus annuus (Sunflower).’’
