Why Washing powder called a basic salt give it one use?

Washing powder is often referred to as a basic salt because it typically contains alkaline substances, such as sodium carbonate (soda ash) or sodium bicarbonate (baking soda), which help to neutralize acids and enhance cleaning efficacy. These basic salts help to break down dirt and grease, making it easier to remove stains from fabrics. One common use of washing powder is in laundry, where it acts to clean clothes by removing dirt, odors, and stains.
