A metal 'M' readily form its sulphate . Which is water soluble. It form oxide MO which becomes inert, on heating. It forms insoluble hydroxide which is soluble in NaOH . The metal ' M ' is-
Options:
Answer:
D
Solution:
The metal 'M' forms a water-soluble sulfate, MSO₄. Its oxide MO becomes inert on heating, and its hydroxide is insoluble but soluble in NaOH, indicating amphoteric character. Among the given options, only Beryllium (Be) exhibits these properties. BeO is amphoteric and inert after heating, and Be(OH)₂ is amphoteric, dissolving in strong bases like NaOH.
Therefore, the metal 'M' is Beryllium (Be).
