Also known as Washing Soda or Sal Soda.
What is it? It is a stronger alkali than baking soda. It is much more caustic (it can irritate the skin) and is generally sold as a cleaning product, not a food product.

Though they share a similar name and appearance, soda crystals and baking soda are distinct chemical compounds with very different uses in the home. While baking soda is a gentle kitchen staple, soda crystals are a heavy-duty cleaning agent.

Cleaning Power: Soda crystals (also known as washing soda) are significantly more alkaline than baking soda. This makes them excellent for shifting grease, cleaning patios, or unclogging drains, whereas baking soda is better suited for light scrubbing or neutralizing odors in the fridge.
Laundry and Water Softening: Soda crystals are widely used to soften water and boost the efficiency of laundry detergents by removing calcium and magnesium.
Baking: Baking soda is a leavening agent that produces carbon dioxide when mixed with acid (like vinegar or buttermilk), causing dough to rise. Soda crystals should never be used in baking. Growing Baking Soda Crystals
Beyond practical uses, baking soda is popular for science experiments because it can form delicate, snowy crystal structures.
