Question

Most suitable salt which can be used for efficient clotting of blood will be:

• A. Mg(HCO₃)₂
• B. FeSO₄
• C. NaHCO₃
• D. FeCl₃

Answer 1

The correct option is D

FeCl₃

The explanation for the correct answer:

(D)FeCl_3,

1. A negatively charged solid, blood.
2. According to the Hardley–Schulz law, a majority of positive ions are required for the effective deposition of a negatively charged sol.
3. The most effective salt used for effective blood coagulation is salt, a cation with a higher charge will have a higher coagulation power.
4. FeCl₃ is most effective for blood clotting.

The explanation for the incorrect answer:

(A)Mg(HCO₃)_2,

Mg(HCO₃)_2, (Magnesium) doesn't have a maximum positive valency, there won't be much coagulation.

(B)FeSO_4,

FeSO₄ mineral is necessary and is frequently used to treat aneamia rather than to aid in blood coagulation.

(C)NaHCO_3,

NaHCO₃ reduces blood acidity and has been used to treat heartburn and acid reflux.

Therefore, option (D) is correct.
