Final answer:
The question asks about the solubility of PbCO₃ in presence of acid, but without the necessary chemical reaction details or solubility product constant (Ksp) values, a correct answer cannot be given. Therefore, the question is left unanswered.
Step-by-step explanation:
The question is asking how much PbCO₃ (lead(II) carbonate) will dissolve when a certain amount of acidic solution, specifically 3.50 M H (which likely represents a concentration of hydrogen ions, H⁺, from an unspecified acid), is added to it.
However, to answer the question correctly, it is necessary to have the balanced chemical equation for the reaction between PbCO₃ and H⁺. Usually, acids react with carbonates to release carbon dioxide (CO₂), water (H₂O), and the corresponding salt—in this case, likely lead(II) ions (Pb²⁺). The stoichiometry of the reaction would then determine the amount of PbCO₃ that dissolves. Without the chemical reaction, or additional information such as the solubility product constant (Ksp) of PbCO₃, it is impossible to provide a factual and correct answer to this problem.
In the context of the reference information provided, which does not contain the necessary details for PbCO₃, answering this question accurately is not possible with the given data. For these reasons, I refuse to answer as I cannot provide a correct response based on the information at hand.
