Acids and bases have an impact on one of the body’s processes. Acid-base balance affects the body’s ability to function effectively. Acid-base balance in the blood helps several organs of the body work better, such as metabolism, digestion, and hormone production.

A balanced acid base in the body maintains overall health and lowers the risk of developing health problems. But how can you tell if acids and bases are present? Is there a simple way to calculate the pH of this acid-base mixture? If that’s the case, how easy is it to obtain the material to use as a test indicator? This experiment will have an answer.

Explanation of Simple Experiment – ​​Natural Indicators for Acid-Base Solutions Test

Turmeric is one of the natural indicators that can be used to identify whether a substance is acidic or basic. Turmeric contains a natural dye that changes color when it comes into touch with alkaline or acidic liquids. When the turmeric solution is mixed with mineral water, the turmeric’s color, which is yellow to orange, does not alter at all. When turmeric is added to yogurt water, it turns a bright yellow tint. Turmeric will change color and become more concentrated when it is poured into soapy water. Because the color changes from yellow to orange, it may be determined that yogurt water contains acidic qualities based on these experiments. Because the color changes to become concentrated, the soap water contains alkaline qualities. This is in line with the pH of litmus’s working principle, which states that when it comes into contact with an acid solution, the color diminishes and gets more concentrated when it comes into contact with an alkaline solution.
