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.

Explanation:
Answer:
2.5 mol·L⁻¹
Explanation:
Ca(OH)₂(aq) ⟶ Ca²⁺(aq) + 2OH⁻(aq)
I/mol·L⁻¹ : 2.5 0 0
C/mol·L⁻¹: -2.5 +2.5 +5.0
F/mol·L⁻¹: 0 2.5 5.0
Ca(OH)₂ is a strong electrolyte. It dissociates completely in solution to form ions
Initial
Assume you dissolve 2.5 mol of Ca(OH)₂ in enough water to make 1 L of solution.
In the instant before it dissociates, you have a 2.5 mol·L⁻¹ solution of Ca(OH)₂ and no Ca²⁺ ions.
Change
The Ca(OH)₂ is dissociates completely into ions. You lose 2.5 mol of Ca(OH)₂ and form 2.5 mol of Ca²⁺.
Final
You end up with no formula units of Ca(OH)₂ and 2.5 mol of Ca²⁺.
