Ionic Compounds and Their Properties

The video tutorial explores whether sodium carbonate (Na2CO3) is an electrolyte or non-electrolyte. It begins by identifying sodium carbonate as an ionic compound composed of metals and non-metals. The structure of ionic compounds is discussed, highlighting the presence of positive and negative ions. The video explains that electrolytes are compounds that dissolve in water to produce ions, allowing electricity to flow. Sodium carbonate is identified as soluble, breaking into Na+ and CO3 2- ions, making it a strong electrolyte. The tutorial concludes by confirming that sodium carbonate conducts electricity when dissolved in water.
