The correct Answer is:
To solve the problem of preventing the adsorption of soluble barium after the administration of barium nitrate (`Ba(NO3)2`), we need to consider a substance that can react with barium ions to form an insoluble precipitate. The best choice in this scenario is sodium sulfate (`Na2SO4`), which reacts with barium ions to form barium sulfate (`BaSO4`), a white precipitate that can be easily removed from the body. ### Step-by-Step Solution: 1. **Identify the Problem**: A patient has been administered barium nitrate, which is soluble and can lead to barium toxicity. The goal is to prevent the absorption of barium ions in the body. 2. **Understand the Chemistry**: Barium ions (`Ba^2+`) can be precipitated out of solution by forming an insoluble compound. We need to find a suitable reagent that will react with barium ions to form such a compound. 3. **Choose the Appropriate Reagent**: Sodium sulfate (`Na2SO4`) is known to react with barium ions to form barium sulfate (`BaSO4`), which is insoluble in water. The reaction can be represented as: \[ Ba(NO3)2 + Na2SO4 \rightarrow BaSO4 \downarrow + 2 NaNO3 \] Here, `BaSO4` is the precipitate that will form and can be removed from the body. 4. **Conclusion**: Administering sodium sulfate to the patient will lead to the formation of barium sulfate, effectively preventing the absorption of soluble barium. 5. **Final Answer**: The best option to prevent the adsorption of soluble barium is **sodium sulfate (`Na2SO4`)**.

A solution which remains in equilibrium with undissolved solute , in contact , is said to be saturated . The concentration of a saturated solution at a given temperature is a called solubility . The product of concentration of ions in a saturated solution of an electrolyte at a given temperature is called solubility product (K_(sp)) . For the electrolyte A_(x),B_(y) with solubility S. The solubility product (K_(sp)) is given as K_(sp) = x^(x) xx y^(y) xx S^(x-y) . While calculating the solubility of a sparingly . soluable salt in the presence of some strong electrolyte containing a common ion , the common ion concentration is practically equal to that of strong electrolyte containing a common ion . the common ion soncentration is practically equal to that of strong electrolyte . If in a solution , the ionic product of an electroylte exceeds its K_(sp) value at a particular temperature , then precipitation occurs . If two or more electrolyte are presentt in the solution , then by the addition of some suitable reagent , precipitation generally occurs in increasing order of their k_(sp) values . Solubility of some sparingly soluable salts , is sometimes enhanced through complexation . While we are calculating the solubility of some sparingly or pH of an electrolyte , the nature of cation of anion should be checked carefully whether there ion (s) are capable of undergoing hydrolysis or not . If either or both of the ions are capable of undergoing hydrolysis , it should be taken into account in calculating the solubility . While calculating the pH of an amphiprotic species , it should be checked whether or not cation can undergo hydrolysis . Total a_(H^(-)) = sqrt(K_(a_(1)xxK_(a_(2)))) (if cation do not undergo hydrolysis ) a_(H^(+)) = sqrt(K_(a_(1))((K_(w))/(K_(b)) - K_(a_(2)))) (if cation also undergoes hydrolysis ) where symbols have usual meaning .
