求翻译：②加热时，浓硫酸可以与除金、铂之外的所有金属反应，生成高价金属硫酸盐，本身一般被还原成二氧化硫Cu+2H2SO4(浓)=加热=CuSO4+SO2↑+2H2O 2Fe+6H2SO4(浓)=加热=Fe2(SO4)3+3SO2↑+6H2O在上述反应中，硫酸表现出了强氧化性和酸性。是什么意思？ 待解决

② When heated, concentrated sulfuric acid can react with all metals except for gold, Platinum, generating high metal sulfates, itself was restored to the sulfur dioxide Cu+2H2SO4 (thick) = heating =CuSO4+SO2 ↑ +2H2O 2Fe+6H2SO4 (thick) = heating =Fe2 (SO4) 3+3SO2 ↑ +6H2O in the above reaction, sulfur
