The ability of sodium sulfate to act as an antidote to barium chloride poisoning is because displaces barium in barium chloride to form sodium chloride and insoluble harmless barium sulfate.
<h3>Why is a solution of sodium sulfate used as an antidote?</h3>
The ability of sodium sulfate to act as an antidote to barium chloride poisoning is because of the reactivity of sodium.
Sodium is a more reactive metal than barium, so it displaces barium in barium chloride to form sodium chloride and insoluble harmless barium sulfate.
The equation of the reaction is given below:
- BaCl2 + Na2SO4 ----> BaSO4 + NaCl
Therefore, the ability of sodium sulfate to act as an antidote to barium chloride poisoning is because displaces barium in barium chloride to form sodium chloride and insoluble harmless barium sulfate.

Answer:
The answer to your question is: 1.61 l
Explanation:
Data
Volume = ?
Molarity = 4.5 M
# of moles = 7.25 mol
Molarity = # of moles / volume
Volume = # of moles / molarity
Process
Volume = 7.25 moles / 4.5
Volume = 1.61 liters
