I wanted to figure out why an acid would react with a base. I had to think of a way to demonstrate this. However, this experiment obviously couldn’t involve rocks dissolving because I didn’t want to wait for generations to get results. I did this experiment in under a week and figured out why an acid dissolves a base. Erosion is a natural process by which acidic rain degrades solid objects on the ground. I realized that demonstrating erosion would be nearly impossible because it would take a long time. However, it is possible to show how something acidic can degrade a solid object when exposed to it over a period of time. I thought of using hydrochloric acid but then decided that HCl was too acidic and it would not prove my point. Instead I decided to use lemon juice, vinegar and pure water for a control. The solid object I was going to use was chalk. I started the experiment by placing three identical pieces of chalk over, chalk, acid, vinegar, lemon, juice, experiment, acidic, time, solid, people, out, object, going, glasses, decided, because, week, water, rocks, results, rain, possible, place, period, mirrors, made, inventions, invention, however, generations, frames, figure, exciting, dissolve, came
