Q2 HIDRÓLISE DE SAIS - ENEM PPL 2023

Q2 SALTS HYDROLYSIS - ENEM PPL 2023 (Enem PPL 2023) Soil nutrient availability (fertility) is associated with the ability to provide essential nutrients to plants, which is dependent on soil pH. Agricultural cultivation for most plant species develops adequately at a pH close to 6. To this end, rural producers carry out agricultural practices and soil management in order to minimize the harmful effects of aluminum, manganese and excess iron, in addition to enhancing the availability of other nutrients, such as calcium, potassium, magnesium and phosphorus. Consider an alkaline soil in which it is desired to carry out management in order to adjust the pH and increase its fertility. CARDOSO, E. J. B. N.; ANDREOTE, F. D. Soil microbiology. Piracicaba: Esalq, 2016 (adapted). The compound that can be added to the soil to meet this need is a) KNO3. b) CaCO3. c) Na3PO4. d) Al_2 (SO_4 )_3. e) (NH4)2SO4.
