Consider the sulphates of alkali metals (). Which of the following statements characterize their beh — s Block Elements Chemistry Question

💡 Solution & Explanation

Alkali metal sulphates are highly stable to heat and generally melt without decomposing, so B is false. When fused with carbon, they undergo reduction to sulphides ($M_2SO_4 + 4C \rightarrow M_2S + 4CO$). Due to its small size, $Li_2SO_4$ is anomalous and is not isomorphous with the other alkali metal sulphates, nor does it form alums.
