검증된 단계별 안내1
Identify the reactants: silver (Ag) and sulfuric acid (H2SO4).
Recall that sulfuric acid is a strong acid that can react with metals to form salts and hydrogen gas, but silver is a relatively unreactive metal and does not typically react with sulfuric acid to release hydrogen gas.
Consider the possible products: silver can form salts with the sulfate ion (SO4^{2-}), resulting in silver sulfate.
Write the formula for silver sulfate by combining silver ions (Ag^{+}) with sulfate ions (SO4^{2-}). Since sulfate has a charge of -2 and silver has a charge of +1, two silver ions are needed to balance one sulfate ion, giving the formula \(Ag_2SO_4\).
Conclude that the salt formed when silver reacts with sulfuric acid is silver sulfate, with the chemical formula \(Ag_2SO_4\).
