Plants absorb mineral elements from the soil in solution with water however these elements exist in the soil as compounds or non- charged atoms. Rain water also dissolve some of these elements to form dilute acids that also react with the mineral compound to release these metallic ions and radicals that plants need for proper growth.
Questions;
a. Using free metals such as Magnesium, Zinc and Calcium write word equations to show how they react with dilute hydrochloric acid.
b. Using oxides of the metals in (a) above, write word equations to show how they react with dilute hydrochloric acid.
c. Describe one chemical reaction that can be used to remove soil acidity.​
