Abstract	Corrosion, which used to be a problem mainly studied by metallurgists and chemists, is now a topic that involves many different areas of study. This is because metals are used in almost every part of our lives. It's important now more than ever to pay attention to how metals corrode. The use of metals has increased a lot in all areas of technology. New types of strong alloys are being used, and these are often more likely to corrode in certain ways. Most of the chemicals used to stop corrosion are expensive and can be harmful to living things and the environment. That's why it's important to find cheaper and safer alternatives to use as corrosion inhibitors. Using natural substances to stop metal corrosion in acidic or basic conditions is a new trend. Inhibitors are crucial in slowing down the process of corrosion. There are many different types of inhibitors, including organic ones, which often contain nitrogen, oxygen, and phosphorus. Inorganic inhibitors form protective layers on the metal surface. Plant-based inhibitors, which are biodegradable, contain chemicals from plants that help slow down corrosion. These inhibitors work by slowing down either the anodic or cathodic reactions, or both. This study focuses on mixing organic, plant-based, and inorganic substances to control corrosion on mild steel in a 0.5M HCl solution. The weight loss method showed 89.39% inhibition for 4 ml, 70.06% for Tafel, and 79.75% for impedance for 4 ml at room temperature.
