Assertion: Gastrectomy can lead to iron-...

Assertion: Gastrectomy can lead to iron-deficiency or anaemia.
Reason: HCl of gastric juice converts `Fe^(3+)` into `Fe^(2+)` which makes iron absorbabale.

A

If both assertion and reason are true and reason is the correct explantion of assertion

B

If both assertion and reason are true but reason is not the correct explnantion of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Gastrectomy**: - Gastrectomy is a surgical procedure that involves the partial or total removal of the stomach. This can be done for various medical reasons, including stomach cancer. - **Hint**: Remember that gastrectomy can be partial or total, affecting how the body processes food. 2. **Impact on Iron Absorption**: - The stomach plays a crucial role in the digestion and absorption of nutrients, including iron. When part or all of the stomach is removed, the production of gastric acid (HCl) is reduced. - **Hint**: Consider how the stomach's role in digestion changes after its removal. 3. **Role of HCl in Iron Absorption**: - HCl in gastric juice converts ferric iron (Fe³⁺) into ferrous iron (Fe²⁺), which is the form of iron that is more easily absorbed in the intestines. - **Hint**: Think about the chemical forms of iron and how their solubility affects absorption. 4. **Consequences of Reduced HCl**: - With less HCl produced after gastrectomy, there is less conversion of Fe³⁺ to Fe²⁺. This can lead to decreased iron absorption and subsequently result in iron deficiency or anemia. - **Hint**: Reflect on how changes in stomach acidity can impact nutrient absorption. 5. **Conclusion**: - Therefore, the assertion that gastrectomy can lead to iron deficiency or anemia is true. The reason provided, stating that HCl converts Fe³⁺ to Fe²⁺ making iron absorbable, is also true and correctly explains the assertion. - **Hint**: Evaluate the relationship between the assertion and reason to determine if they support each other. ### Final Answer: Both the assertion and reason are true, and the reason is the correct explanation of the assertion.

A 3.00 g sample containing Fe_(3)O_(4), Fe_(2)O_(3) and an inert impure substance, is treated with excess of KI solution in presence of dilute H_(2)SO_(4) . The entire iron is converted into Fe^(2+) along with the liberation of iodine. The resulting solution is diluted to 100 mL.
