According to one acid base theory the forward reaction is classified as an acid base reaction because H2S is a H donor and CH3NH2 is a H acceptor.
According to the acid base theory; an acid is the proton donor or hydrogen ions donor while the base is the proton acceptor or hydrogen ion acceptor.
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:
atomic number
Each period, numbered one through seven, contains elements of increasing atomic number. Unlike Mendeleev's original list, the modern periodic table is based on atomic number, or the number of protons in an element's atomic nucleus
Explanation:
