[00:00:00]Science alert. A mysterious chemical event has occurred inside Hero Tower.

[00:00:05]During lunch, our genius scientist spilled curry on his favorite white uniform. But when he washed it with soap, something impossible happened. The yellow stain turned reddish-brown.

[00:00:18]The curry contains turmeric. Turmeric is not just a spice. It can act as a natural indicator. Indicators help us identify whether a substance is acidic or basic. Turmeric changes color when it comes into contact with bases. Soap is basic in nature. That is why the yellow turmeric stain changed into a reddish-brown color. Let's test the theory. When turmeric is mixed with water, it stays yellow. But when soap solution is added, it changes to reddish-brown. This proves that soap is a base.

[00:00:50]When the shirt is rinsed with water, the soap is removed. Without the base present, turmeric returns to its original yellow color.

[00:00:58]Welcome to the battle of zing versus slippery. Acids are often sour, while bases feel slippery. Team zing includes lemon juice, vinegar, and stomach acid.

[00:01:09]They are acidic substances and often have a sour taste. Team slippery includes soap, baking soda, and detergents. These substances are bases.

[00:01:18]Sometimes our stomach produces too much acid, causing indigestion. A base, such as baking soda, can help neutralize excess acid. Neutralization occurs when an acid reacts with a base. Indicators are chemical detectives. They reveal whether a substance is acidic or basic by changing color. Blue litmus turns red in acids. Phenolphthalein turns pink in bases. Methyl orange becomes red in acids and yellow in bases. Many indicators come from nature. Plants and flowers can reveal whether substances are acidic or basic. Mission complete.

[00:01:52]You solved the curry stain mystery and discovered the secrets of acids, bases, neutralization, and indicators.
