WebThe formula of red copper(I) oxide can be determined by reduction with hydrogen in exactly the same way as for copper(II) oxide. The colour change is less clear-cut, but the powder glows, showing that reduction is taking place. Oxides of lead can be reduced by this method using hydrogen, as can other metal oxides

Web30 de jun. de 2024 · In the case of lead (IV) oxide, the reaction requires ice-cold hydrochloric acid. If the reaction is carried out at warmer temperatures, the lead (IV) chloride decomposes to give lead (II) chloride and chlorine gas.

WebAnswer: This is a very interesting question! Lead(ii) oxide is PbO and it is generally colored red before heating. The red PbO is a stable compound. However, by heating the red PbO, we can create yellow PbO, which is a meta-stable compound. PbO (red) +1.6kJ/mol = PbO (yellow) [T ~ 500C] This i...
