Na2co3 dissociation.

Na2CO3 is an ionic compound composed of sodium ions (Na+) and carbonate ions (CO3^2-). In an aqueous solution, these ions dissociate, meaning they separate from each other and become surrounded by water molecules. This dissociation process is what gives rise to the high conductivity of Na2CO3.1 molecule of Na 3PO 4 dissociates to give 3 sodium ions. The number of moles of Na + ions present in 20 mL of 0.40 M Na 3PO 4 = 100020 × 0.40×3=0.024. Thus, 0.024 mol of Na + ions are present in 20 mL of 0.40 M Na 3PO 4.Dissociation Reaction: The problem wants to know the dissociation of the sodium sulfide compound.
